The heater fan in the van will only work on full blast and the rear wiper/ ac button lights flash which I had another 98 caravan that I was driving that had the same issue with the flashing lights. What is that all about?
View 2 RepliesI have a 2006 Sonata and just a few weeks ago the AC/Heater Blower would only work on full blast. You actually had to have the control set a little before the full setting to get it to come on. Both the heat and the AC worked. Now, nothing is coming out on any speed setting. I've replaced the blower resistor and checked the fuses/relay and they seem fine.
View 2 RepliesI have a 2006 Dodge Caravan, My AC unit works great. With the heater, it will work for 2-3 minutes, at which point it starts to blow cool air. I can leave it running, but it never gets warm again, if I turn the fan off for 3-5 minutes, when I turn it back on, I get a good amount of heat that goes for about 2-3 minutes before blowing cold air again.
View 1 RepliesMy heater and a/c on my car have been acting up!
Yesterday I got into my car I turned on my heater and it didn't work! So I pushed the a/c button and that did nothing either! No air came out of the vents at all even on full blast... So I tried turning it off and back on and nothing happen then it finally worked but when i tried to turn it off it wouldn't turn off then randomly turned off by its self!!!
Whats going on and what I should check for this problem ?
I have a 2000 Buick Regal LS. This problem used to be intermittent but has gotten to the point that I never see a "normal" operating state from my HVAC controller unit, so I need to get it fixed. The problem is that when I turn my car on the controller comes up completely blank except the 4 red lights on the passenger side climate control. The heater then (at the same time) turn on FULL BLAST and is stuck in the 90 degree setting (hottest possible). I got to the point that I pulled the high fan fuse just so I didn't die of overheating...
Today I tried to replace the actual controller unit with a refurbished unit I bought off of ebay. Unfortunately, I had the same result with the new controller...No display at all, but all red lights light on the passenger side climate control. My thought is that the issue is much deeper than a vacuum line (although I haven't checked them yet) or even the controller unit. I've checked all the related fuses and they all seem to be fine. Could this be a computer issue? If so what is the fix?
Recently my truck is only blowing heat or air conditioning on full blast in my 2004 Ford F-150 (New style, not heritage).
Level 1, 2, or 3 is exactly the same and blows almost nothing, then if I switch it to 4 it is full power.
I just don't know what exactly I will need to change. I know it would be a resistor pack somewhere that probably failed, I just don't know where it would be.
Do I just need a new control switch, or do I need a new heater fan?
I have a 2005 Dodge Caravan with a heater blower that doesn't seem to be working. Whether the heater knob is on low or high, it does nothing, but you can feel a little heat coming out, though. I was told it may be a resistor behind the glove box. I've already checked the fuse, and it seems OK. What do I do?
View 6 RepliesI have a 1998 Plymouth Grand Voyager SE. It has 122000 mi. I just bought it a few months ago and have came across a few minor problems and all have been easy DIY projects (couple of blown fuses, wiper replacement etc..) Recently, I noticed the AC stopped working (it was only tested once when I bought it, but have not used it since)
Where to begin the diagnosis. Is there a fuse connected to the functioning of the AC? I really don't know a whole lot about cars, but I am pretty good at fixing things in general.
I took the van on a road trip and the engine seems like it wants to stall at lights. the idle stays at 500 rpm or so most of the time while at stops. there appears to be no way to adjust the idle and there is no Czech injun light on.. what could the problem be? the engine is a 3.8l

View 8 RepliesI'm about to put a new tailgate on a 98 Dodge Caravan. I got hit in the back and I bought a new back door at the junk yard. It looks pretty easy, but I thought I would touch base here and there are a couple of potentially tricky parts...
Does that wire bundle have a block somewhere that you can plug, or am I going to be splicing them one by one? (I don't have power locks. I have windshield wiper, back door inside light, license plate light, heat wires in the glass.) The other tricky part..changing the lock.
I think that's all.. the bolts and star screws look pretty straightforward. I got it used with 48k miles a couple years ago and I only have 75k now. It was a government car.
My father's 1998 Dodge Grand Caravan SE radiator fan runs constantly - even with the ignition off. He has to disengage the battery for the fan to quit running - what might be wrong?
View 14 RepliesI have a 1998 Caravan and the engine cooling fans wont go on. Ive replaced the relay and the temp sensor. When I pull the connector off the temp sensor the fans go on so I know the fans and fuses are fine. For some reason it seems the computer module isnt sending a signal to the relay to turn the fan on. I get the trouble codes P1491(radiator fan relay circuit fault) and P0118(engine coolant temp circuit high input).
I am also having a problem with the air conditioning not working. When I do the self diagnostic test on the A/C the results are that it fails the cool-down test. Why the computer module isn't sending a signal to the relay? Could the A/C problem be causing the cooling fans not to come on?
The battery light came on, alt not charging. I have taken it off twice and had it checked, both times I had it checked it showed good, when I put it back on it charged for a bit and then the light came back on and it showed no charging at the battery. Second time the place checked it they ran the check cycle 4 times in a row to see if it had a problem when the electronics started warming up... still showed all green.
I thought perhaps the wires going to the alt, so I had the wife start the van up and I moved the wires around going to the alt to see if it made the batt light flicker, no joy. (real fun getting your hand back there while the van is running)
The large wire shows batt voltage where it hooks on to the alt, running or not...... the two prong plug that goes into the alt shows no voltage unhooked with the key on, and no voltage plugged in with the key on or running.
I have been told there is a control unit that controls the output of the alternator. I have checked every fuse in the fusebox under the dash and in the engine compartment. Fuseable link on big wire going to the alt should be good as I do get battery voltage to the alt from the battery, correct?
My wife has been driving our 98 Dodge Grand Caravan the last couple of days and while she is driving the Tachometer and Speedometer will drop to 0. This does not affect the performance of the engine or anything else. Runs and drives "perfect" (or at least for its age and mileage). The dash seems to "reset" when she parks and turns off the ignition then restarts it.
View 2 RepliesJust changed the battery on a '98 Grand Caravan 3.3. In the process of tightening the positive terminal I accidentally touched the wrench to the negative. There was a spark, of course, but otherwise no biggie. However, now the HVAC indicator lights, including the rear wiper, defroster, etc. indicator lights, all blink continuously until about 15 minutes of driving, then they return to normal. I disconnected the battery thinking that I needed to clear the PCM but the blinking always returns. Is this some sort of manual code reading deal? If so there's no mention of it in the Haynes manual.
View 14 RepliesIt is as an electronic whistle/humming. The sound is coming from the rear of the van, and no, not when it's moving, even though it still does it when moving. The only thing I can think of would be the fuel pump. Because It's loudest just before the rear tires, not after them. My fiancee has heard it twice now, when she first heard it, I didn't, but this last time when I heard it, I also noticed that the gas gauge was reading just below 1/8 of a tank.
Would like to know if it's the fuel pump or something else I'm no thinking of. And if it means I have to replace the pump.
My 1998 T&C has a problem where the front passenger window keeps falling off the track (caused by hard slamming of the door).
I've gone into the door multiple times to pop the rear-most peg back into the white plastic window track "dog", but it keeps popping out after moderate door slams. Do the black pegs that are glued to the window wear out? (I think they're metal).
I think the plastic track dog is fine, and I make sure the metal clip is fully engaged with the window peg each time I pop it back in. The only reason I can come up with for this problem is that the window peg is worn down and has lost its "edge" and thus the metal clips can no longer retain it. Sound reasonable? Probably need a new window from junkyard correct?
P0032 Oxygen Sensor Heater Circuit High Voltage (Bank 1, Sensor 1)
I have read that in 2005 chrysler changed the ohms levels for the oxygen sensors and may need to have bcm reflashed to get a new oxygen sensor to work wheither its dealer item or not, is this true if i were to buy a mopar oxygen sensor? aftermarket is out of the question being the ohm readings would require me to spend some time at the dealer. is this code a defective sensor? or could it be related to the thermostat being faulty? am not low on antifreeze and temp gauge reads normal.
98 dodge caravan 3.3L v6 ..... All lights work including driver's side tail lights. only problem is that when pressing brake pedal, the driver's side brake light does not light up. i changed the bulb and checked the brake light fuse under the hood, but it was fine (as i guessed since the passenger side and middle brake lights work). I took the assembly off and reseated the connector to the tail light assembly, but same issue.
View 2 RepliesAll the electrical components that are controlled by the ignition key/switch (radio, power windows, wipers, AC/fan) sometimes don't work when I turn the van on. However, when the key is turned back into accessories position, everything works - never a problem then. I had the ignition switch replaced a few months ago and that seemed to work (didn't occur as often) but now it's back to the way it was before. Just about every time I need the wipers (when it rains), they don't work nor do any of the other things I mentioned previously.
