Quick question about the heat coming out of the AC issue

[stevek]

I know this means that an actuator for one side of the air conditioner is out, but is there a way a dealer can find a trouble code for it being broken/stuck?

yep...good luck with this one. im going thru the same problem but i refuse to let the dealer **** me...lol i just changed my recirculation actuator and took it them to have them recalibrate it and still didnt fix it. they say that the actuator wont keep the a/c from working tho. let me kno what u find out

ok sorry to but in but my 01 just started messing up too...like when its cool outside in the mornings or at night my AC blows cold as hell but as soon as it gets warm out its blowing straight heater...changed out my fan clutch and added freon and it worked better for like 2 days then went right back to blowing hot...compressor is working and the compressor clutch is coming on...what actuator are yall talking about?? i work in the gulf of mexico so im not going to be around my truck for another 3 weeks but im trying to trouble shoot as best i can before i end up taking it someplace when i get home...

i believe you have 5 actuators. 3 behind the dash and 2 behind the right rear quarter panel for the rear a\c.

behind the dash you have
1) Recirculation/Air Inlet Actuator
2) Mode Door Actuator
3)Temperature Door actuator

this is for the automatic a/c and heat controls though. also dont kno if it makes a difference but i have the digital controls as well. im not sure if its all the same or even if its the same for 01. i believe the 01 is different but i could be wrong.

There should be one for the driver and another for the passenger side. But is there any way this could throw a code?

If it does throw a code, only the dealer will be able to read it with a Tech 2. A code reader will only read engine codes.

Im not sure if this applies to you but it maybe worth a shot. My rear vents were stuck on hot even after switching it to AC using the climate controls. It turns out that the actuator was traveling too far to the point of no return. After drilling a bolt into the actuator to act as a stopper everything worked out just fine!

I know that. I want to know if it is possible to throw a code even for that
