2012 6.2 XLT 50,000 miles with manual single zone controls. I haven't had time to work on it yet, but it seems that my AC compressor is not engaging. The dash controls light up normal, fan comes on, etc. I am just looking to see if there are any common failure points. I know it COULD be low on charge, clutch could be bad, etc. I am just checking if there is a common failure with these trucks AC system.
View 10 RepliesGot in my truck this morning and everything worked fine, no problems. Arrived at my destination and parked. Come out about two hours later start the truck and my A/C wont blow air, My truck is an 05 lariat so it has the climate control A/C. Everything was working fine it just wont blow air, When i turned the A/C on and off i could hear/feel the small thump of the clutch engaging on the compressor. I am thinking the blower fan just went south? or maybe something stupid that controls the blower fan? Summer is in full swing here in central florida, temps are 95+ not including the humidity...

View 2 RepliesI have a 2002 Ford Superduty. I recently had installed a BDS 8 inch suspension lift. I also had the upper and lower ball joints replaced. All this work was done by a certified garage. Today i went to pull out my boat from the ramp, turn the switch inside the cab to 4x4 high. The light came on but 4x4 did not engage. As i pulled the boat out of the water the rear tire spun in the sand but the front did not. As i cleared the ramp and on level ground i turn the switch off and back on i heard not but the light can on. With the 4x4 light on i turn the wheel and pulled forward i noticed no hopping as when a truck is in 4x4. Initially when i turn the 4x4 switch on i hear a clunk up front but not after. Drove home drive train appeared fine no noise.

Took the family down to the beach today. Had some tough sand to get across in a few areas to move away from the crowds. Got a little dicey and the truck got stuck in 2WD. Switched to 4WD but back tires kept spinning. Couldn't figure out why and the truck started to dig deeper in the sand. Got a little nervous and I didn't want to start the day off with having to get pulled out.
Got out of the truck, locked the hubs in manually and I was out, no problem. Left the hubs locked until we left the beach and back on pavement.
What might be the problem and why the "shift on the fly" switch on the dash didn't seem to engage the 4WD? I even tried to switch into 4L and back to 4H (truck in neutral, break pedal compressed) and still no workie. Only manually locking the hubs would engage the 4WD.
Truck was running fine up until now. After the WTS light goes out, I crank it and.... nothing. It doesn't even try. It's not a battery problem. I have 12.6 V from each battery before and after cranking. The lights are bright, the horn works, the dash lights are strong and bright all both before and after cranking. It just doesn't want to engage the starter. I tried my backup key as well, thinking it might be a problem with the PATS. No dice. Where to start looking?
View 6 RepliesI'm trying to figure out why my auto locking hubs do not engage. To isolate the problem shouldn't the hub engage if a vacuum is applied to that hub only? A solid 18 inHg is maintained at that hub for over 10 minutes but the selector will not rotate, which suggests to me the seals are OK. What then might be the problem?

View 3 RepliesMy 4x4 on my 2000 model f350 will not engage. The light works, comes on briefly on startup of the engine. When I flip the switch nothing happens. When I jumper the relays nothing happens. I do not have the factory hubs, they r warn hubs and the vacuum line to them is capped off. How to figure this out on why the 4x4 will not engage?
View 13 RepliesMy 2011 F350 is not engaging 4wheel drive from the dash switch. When I turn it to either hi or lo it says "shift in process" but no 4 WD. It will engage manually from the hub lock, no problem. I know very little about 4wheel drive but am otherwise mechanically knowledgeable.
View 5 RepliesI have a 2001 F250 4x4 and the ESOF switch not engaging hubs, currently I have no 4x4 lights coming on in the cluster when i turn the switch. I am not experiencing any of the vaccum symptoms that most people are suggesting. I When I turn the switch i also do not hear any relays clicking. Relays have been tested, and i waited for the 45 second transfer delay that the manual mentions. ESOF switch has power, and is working properly (I know because I bought a new one in attempt to fix the problem) Basically I have no responses from any of my 4x4 indicators or parts.
View 14 RepliesI have a 2000 f250 CCSB 4x4 with the ESOF auto hubs. The auto hubs won't engage automatically. They work fine manually. The transfer case is engaging and correct lights are coming on. There is a little bit of vacuum coming from the vacuum switch but it doesn't seem like much to me. All the dash HVAC controls work fine though. I Lubed and cleaned inside the hubs according to Guzzles directions.
While torn down, I blew through the vacuum port on the outside of the hub and there was little to no restriction. I don't think there is enough vacuum to pull the hubs, but is that possible if all the dash controls work fine? What pressure should it take to engage them? My next step is to pick up a vacuum pump and see if I can engage them with it.
With the few hot days we have had here lately, I have noticed that after about a minute the AC will go warm and I will have to rev the truck up when it does to get it cold again. It seems the compressor is disengaging. I noticed that the condenser has a big gash with a tube ripped open on top. I know it needs to be replaced, but could that be causing the compressor issues? It's a 2003 7.3L.
View 8 RepliesOk AC wasn't working took it to a mechanic told me the the compressor was missing a clutch he recommended i put a new compressor. Is it possible just to put a new clutch in it and if so do i have to remove the compressor to put the clutch on it.

View 13 RepliesI am not sure which it is but I cannot turn the pulley by hand. How do you tell if the pulley is bad or the whole compressor? I went out to start the truck and it wouldn't start. It died so I restarted it and then I seen the smoke from the front of the truck. I opened the hood and the flipping belt was just hanging there. Is there a way to just bypass the unit for now? I wont be needing the AC till summer and that is several months away.
View 3 RepliesTrucks compressor kicks on and off and won't stay on no cold air at all do i have a leak ? The truck came whit a new canister that mounts in front of the air box could it be that?
View 8 RepliesOf course my freon all leaked out of the AC compressor and it is squealing pretty bad. I did not want the serpentine belt to break due to a seized compressor so I looked for a bypass pulley kit. Naturally they make one for both gas engines, but not for the diesel. So out comes the string and sharpie, and trips to 2 different auto parts place to get the correct length belt after trying several that were too short. It's 103 inches (8 groove) for future reference to bypass the ac compressor and upper extra pulley. 7.3 diesel.....
View 7 RepliesYesterday I was parked on an incline with my front wheels on gravel and the rear wheels on wet grass/mud. When I tried to go, the rear wheels started spinning. I then switched on the low 4x4, and tried to go. The rear wheels continued to spin, but the front did not turn. I had new wheels installed, that has a cap that covers the manual locking hub, so I couldn't turn it to lock the hub. What should I look for to fix the problem?

Got a 06 F250 V8 Gas. Went to turn AC on the other week & got warm air out vents. Put 1 can of 134 in & the gauge on the "kit" said it was in the green. It was working last summer. You can turn the compressor "face" so it's not locked up, but it's not kicking in. Swapped the replay with another one & the 10a fuse in the fusebox under the steering wheel is good. Is that the only ones? I find it hard to believe that it's something serious. We did change the belt a few weeks ago & I was hoping that we had pulled a wire loose. The vacuum line that plugs into the heater hoses is plugged in.
View 14 RepliesI have a 2001 F-350 S/D w/7.3. Question is... Is it possible for the mode switch ( one controls floor/ defrost and A/c ) to not function or should I say leave the a/c on even if it is not in a/c position? What I have noticed was that when it is in the floor mode or the vent mode (not the floor/vent) the compressor does not come on. When it is in vent/floor or either a/c modes it does. Is this normal... I don't think so though I do know anytime the a/c is switched on compressor should come on but no time without a/c being on.. Maybe I'm wrong
