Ford Aerostar :: 1994 - AC Blows Cool But Not Cold
Aug 5, 2012
My 94 is on the mend , since I got it a few months ago. The air conditioner blows cool , just not cold . It's still a R12 system, and I got the fittings/R134a/oil charge/and mineral spirits to do the change over, but hesitated when I found someone locally had a few cans of R12 for sale . My thought is to buy 1 can , and see if a shot would make the difference before going through the procedure to flush the 12 out and go with the 134a .
My biggest problem is lack of a gauge set , but a guy from CraigsList here says he walk me through the change over for 60 , and betting he'd have the hoses for a 12 system to hit that if that's how I decide to try first. I just wonder why , since I got it , the "cool" it does blow hasn't changed so I am betting it isn't leaking , but the jackleg I got it from was one that IMHO wouldn't know how to open the hood , or what to leave alone, I am just at that point of impasse, as to which way to go ...

I have a 2004 Buick Century with about 48,000 miles on it..the A/C blows very cool but not cold,it should be colder..i also have a 2003 century that blows icy cold.. I hooked up a cheap gauge to the low side service port on both vehicles and got about the same reading. Other then being slightly low on refrigerant is their anything else that would cause the A/C to blow cool air rather then icy cold? The compressors seem to kick on the same on both vehicles. I really don't want to add refrigerant if it's not low...

I took the dive into a new heater core, as the heater was not getting hot. These are the things I did while on my adventure.
1. Before reinstalling the hoses, I blew thru them to make sure of no clogs...water flew out the other hose..no problem..no clog.
2. inspected mix door not cracked or broken...no problem
3.actuator opens and closes ok, I assume, I can hear the motor run and the door thump closed...no problem
4. water and anti freeze level good....no problem
Start vehicle,let warm up, turn on heat.....No Heat...
5. check hoses at core, one is hot ,the other is not....Problem...
1997 f150 4x4 ...

So my heater works when I'm rolling down the highway. When I'm at about 20 mph or less it blows cool air. Also when it's just idling it blows cool air. What I might have an issue with?

1) no cool air at all from AC
2) low pressure side shows 0 even after adding some refrigerant
3) ac compressor engages. I can hear a slight load on the motor when I push the ac button
4) when pressing the ac button the fans don't automatically come on. They should come on right

I have an '08 350 with less than 82K miles. My problem is the AC. The vents on the passenger side blow out cool air and all the vents on the driver's side blow out hot air. Even the vents in the backseat, the left one blows hot air and the right one blows cool (my son informed me of this as I hadn't even checked). As you can imagine it's very uncomfortable driving around in this CA heat every day, especially since the driver side vent in the center cannot be completely closed. What could cause this?

I have an '02 Durango, and the AC only blows cool air when going down the road at 25+ mph. I thought I'd try putting some refrigerant in, but when I hooked up the gauge on the can it buried the needle, so it's over 100 psi on the low side, and the pressure was high enough that no refrigerant would flow in. Up where the lines attach to the expansion valve, when idling the in line is HOT - like too hot to keep your hand on and the out line is about air temp. The guy at the parts store thought the expansion valve was bad. As stated, AC works okay (but not excellently) while going down the road.

I've read that this is a somewhat common problem but can't find the part number to what I need. My heat stopped working and won't change blowing any temp only blows slightly chilled air. I found that its suppose to be a part in the dash that controls this thru the climatronic head unit some lever that isn't getting pushed over correctly dew to a worn out part. What part I need to get my heat back working.

My 2007 Prius air conditioner blows mainly warm rather than cool air. I took it in for repairs and they replaced the high pressure hose but it is still not cooling the car. The dealer has had the car for 2 weeks trying to determine what the problem is. They tell me it should be blowing 42 degrees but is only blowing 62 degrees. They think that it might be the invertor that cost $1,000.

My air conditioner blows cool air (not cold) when I am driving, and when I am stopped, it is warm air. I had to replace the sensor last year. Could it be that again, or something else? Chevy Tahoe 2003 ..

It is a garage queen 1994 4.0 AWD with 42,000 miles in nearly perfect shape. Except for the dent in the rear on the passenger side.
I have posted a picture of the dash when going down the road. As you see the engine light is on. It comes on intermittently, pulled the codes, indicated MAF, 02 sensor, running lean/rich. Runs like a champ, no hesitation, still gets up and goes, gets the appropriate gas mileage. I replaced the 02 sensor with the original Ford Part. Didn't cause the engine light to stop going on after about 20 to 60 minutes driving, sometimes it doesn't come on at all.
Could this thermostat be running too cool and causing the engine to throw those codes? Would gladly take it to a mechanic, but seems like it might be a fishing trip with my dollars for them. Next I was going to replace the MAS myself, easily done with the original remanufactured part at a cost of 150.00, 70 for the core, but don't want to chase my tail with these engine lights on when it runs nearly perfect.
Have sprayed the MAF. Checked for air leaks anywhere. Done all the things I could do by just lifting the hood.
So the picture shows the Temp gauge barely touching the N flying down the road at 70 on a level surface, outside temp about 60. Reading the posts says they all run in the cool section of the temp gauge.
So the question is, do they run this cool? Heater works fine and the gauge goes up past the N resting before the O when going up hills on the way to Tahoe. Is this a thermostat problem on a 20 year vehicle with low mileage, or am I going to have to bite the bullet and let the mechanic go wandering through the vehicle?

Was driving issue free most of day, when leaving a red light I noticed my i had to give the van some extra gas to get up and go, then i could feel the brakes getting tighter and tighter to the point where I had to park the van. So currently my van is sitting in a parking lot 30 miles from home with locked up front brakes. Both driver and passenger front wheels were hot to the touch.

1994 - 3.0 .... Back behind the water pump there is a stream of coolant what could that be. Water pump has been replaced earlier last year I thought that fixed it,there has always been a mystery leak..

2 or 3 years ago my airbag light started blinking. 120,000 miles, only owner. The code changes daily. Then the car started reviving at highway speeds. Then cruise control wasn't reliable. Sometimes when I hit a bump, the cruise goes off. My mechanic said the reviving felt like it was going in and out of overdrive, so he rebuilt the transmission. No change. This past month, the car started to pull to the right. It felt like I was driving with the brake on, couldn't get up a small hill. Before I could get the car home, the brakes went to the floor and the car stalled. I had it towed to mechanic.
After 10 days, he couldn't duplicate problem, so I took the car back. A few days later, after 4 hours of errands in the hot Texas sun, it did it again for me. Pulled to the right, driving with the brake on feel, brakes to the floor. This time it smelled like something was burning, either brakes, belt or something, and the rear ABS light came on for the first time. Latest mechanic says it is probably a brake booster, but that doesn't explain the reviving does it? I've had it to 2 dealers, 3 mechanics, and no one has a clue what to check apparently. I am a senior, so I can't really start replacing everything. What should I tell them to check, and in what order? I love my Aerostar....

Srange noises of my 1994 AWD. When driving, if I take off fast, it makes a lot of pop noise, but if I take off slowly, then It's Ok. Or when I make a quick acceleration after slowing down then it make noise, but if I take it fairly slow then it's OK. The frequency is getting worse. My front axles are in good condition (30K miles on a rebuilt pair). I have unplugged the AWD controller box, it didn't do any difference. All gear shipped OK. So what is that noise in that condition? My 94 AWD is about 110k miles, good shocks.

About two years ago I sold my 1994 Aero (transmission was going, and other stuff) and bought a 1997 that was in much better shape. But one flaw it has is that it was used somewhere with high corrosion, so a lot of stuff is stuck or rusty. I haven't changed the rear bulbs since I got it, but this week, 2 out of three bulbs went. Actually, I only noticed the 2nd one because the blinker went too, and started blinking fast. The 3rd Brake light on top might have been out a while already.
Anyway, to my frustration, I cannot open the 3rd Brake Light to change the bulbs. Even after I removed the 2 screws, the lens won't budge. I tried gentle prying, but I can hear the plastic starting to crack. I figure there are 2 possibilities.
a) It somehow got fused to the gasket over time. or
b) It was crazy-glued shut by some insane maniac (a long-shot?). In which case I can try Acetone.
For starters, once the screws are removed, does just the red lens come out, or does the black frame around it come out with it? I tried prying on both, but one of them is surely wrong. Worst case scenario is that I break it, and have to glue it back on or get another one from a junk yard. But that is not good... Meanwhile I am living ok with just 2 brake lights.

My 1994 Aerostar, with 100,000 miles on it, started lurching at highway speeds. Weeks before this, the airbag light began blinking. The transmission man said it felt like it was shifting into overdrive, then out, then into overdrive, then out, etc.,etc. About this time, the cruise control quit being reliable. Dealership said codes didn't show a problem, "I must be mistaken". Then they said it sounded like a fuel filter.

I just bought a 94 Anniversary Edition that came with an aftermarket remote start. I upgraded the module so I could get better range and would like to connect the rear window defrost to it. I have the trunk release feature on the module and since it isn't in use figured I could use that function for the defrost. The module has a negative output. What wire in the defrost switch would I connect to and would I need a relay to convert the negative pulse to positive? The winters here get extremely cold.

I have a Buick park avenue 1998, 3.8L V6 engine. the problem is: The ac vent on the driver's side blows cold air but on the passenger side blows EXTREMELY hot air. no matter how cold or hot you set the ac it blows at the same temperature on both sides. Florida heat is setting in and my passengers are melting. I am really hopping that is not something to bad and that I can fix it myself. Tip: this started happening after i had the alternator and the battery replaced.

Starting a hot engine in my 94 3.0L RWD occasionally produces a low- pitch 'wah-wah-wah' groaning noise that goes away after 3-4 seconds. It sounds like it's coming from the engine itself and what I'm hearing is an engine running without sufficient oil. It has never happened on cold starts, but about 30-40% of the time when restarting, like at a gas station after fill up, etc. I live in sunny San Diego so I put 10W40 in at the last oil change. It's also currently overfilled by about a quart--I intend to remedy, but have not gotten around to it yet. Could it be the viscosity or quantity of oil? It's a real sphincter puckerer of a sound and I want to get it resolved.

Looking for the fuse that controls the overdrive torque converter clutch/lock up/engagement. Had a look in the owner's manual, didn't find anything. Pulled a couple fuses that I thought might be the one, no go.
I had found this fuse b4 but now a couple years later can't remember which one it is and can't remember where I found the info on what # the fuse was.
