03 Tahoe a/c evaporator core - The 1947 - Present Chevrolet & GMC Truck Message Board Network

biggsteve97 · 06-12-2013, 05:11 PM

I have a 2003 Chevy Z71 Tahoe and both a/c evaporator cores have failed. Does anyone have or know where I can find the information to replace the front evaporator. I know from seeing an 03 Suburban Z71 in our shop that had the same problem, they had to pull the seats, floor console, and the entire dash. I am really really not looking forward to this repair but i would like to read up on it before hand so there are no surprises later. The rear evaporator core looks pretty straight forward especially since I do not have the third row seat. Any help would be greatly appreciated.

sounds like you got everything you need it all has to come out. might as well replace the heater core while you have it apart!

Well, I have never pulled a dash out of one of these trucks/suvs before and the last thing I want/need is to mess up the wiring or forget where something goes. That is why I am trying to find the information on how to replace the front evap core. I tried to get the guys here at the shop to give me a print out from ALLDATA but they have been so busy they keep forgetting. I do not have access to it or I would do it myself.
