AC switched to HEAT while driving. PLEASE HELP

[OneLuv1979]

I am in South Florida and its starting to get real hot outside.
I have owned my 2004 escalade for all of maybe 2 weeks.

I was on the interstate today driving and all of a sudden my cold air switched to HEAT.I did everything trying to get the cool air back adjusting controls with no luck it just continued to blow hot heated air.

30 miles later when I got off I95 I shut the car off and restarted it and bam AC is blowing ice cold again.... Can someone please tell me what the heck I need to do to repair this. Bummed to be already dropping cash on it , I spent everything I had buying it.

The blend door on that side needs to be changed. There is a blend door for the driver side, passenger side, and rear for temp. Did it do it on both sides or just the drivers side?

There are 48 threads dealing with the blend door actuator in the "interior" section.

Here is the specific "how to" to change them

VERY common problem for GM... Just change that out and you'll be golden.

While I was in school last semester I changed probably 5 of these things and with the same symptoms as you.

Glad to hear.... I will read over the threads later.. Just checked my thread quick after dinner.
gotta go put the kids to bed.

How long or hard of a project is it to repair the drivers side actuator?

 

[Big Buttons]

Electronic modules now days aren't meant to be repaired really... its cheaper and faster to just R&R.

 

[OneLuv1979]

I did not notice is it did it on both sides...
Hopefullu just the one side ...but I will have to wait to see

 

[Big Buttons]

Do you have dual front climate control? like can the driver and front passenger have different temps?

 

[OneLuv1979]

Yes it has climate control.

Question where is the drivers side actuator located?
The link I was given just says the passenger is under the kick panel...
BUT another thread says its behind the radio?

 

[NathanJax]

behind radio. You'll have to pull the dash topper to get to it

 

[OneLuv1979]

I know im a rookie but I think you are incorrect.

I have had a few people on other sites tell me drivers side is under the kick panel.
Does anyone have a repair manual that can verify?

Wow you must have had a few too many beers my man!!! LoL

The link you gave me only confirmed that the passenger actuator is located under the dash.... As they are clearly taking the dash apart and the title of it says "2004 Chevrolet Silverado, Changing The Passenger Side Blend Door Actuator"....

Every link you have me confirmed you were backwards.
The drivers side actuator is located under the kick panel and the passenger under the dash behind the radio....

No Biggie you still helped me figure out...
Just confused me with the first link you gave me as he stated the passenger is under the kick panel.....

Thanks

 

[NathanJax]

Actually, I read your post backwards. I thought you were asking for the passenger side, not the drivers side. Sorry about that.


either way.... now we know where they are!!!!

Has anyone used the dorman actuator?

 

[03z71chevy]

I would personally just buy an AC Delco part. I got a new one on ebay for right around $100 if I remember correctly. From what I have read the dorman parts can be hit or miss and if you shop around a GM part won't be too much more.

 

[NathanJax]

I used AC Delco when I had my 04 Esky

 

[OneLuv1979]

LOL Its ok the links you provided about the dash are saved on my favorites.
They might come in handy down the line.

Glad its the easy one and its making the clicking noise under the kick panel...
Is there any chance you guys might know the part number?
I would rather order the correct part , and remove and reinstall.
