Hi everyone, have a question regarding the air conditioning evaporator core in my truck. I have a 2003 standard Escalade (not ESV or EXT). I had a leak I hadn't been able to track down, so I put an entire can of refrigerant w/ dye in it through it to see if I could spot where the dye was coming out from. Well, I found it.
That little vent you see dead in the center of the pic (with the light on it) leads straight into the firewall. It's located right under the accumulator, looking up from underneath the truck. The stain on it is the dye. So, it looks like I get to swap out the front evap core.
My question is - what one do I need to get? My truck has electronic HVAC controls with an auto setting, but manual knobs for the rear A/C. Factory center console. I have RPO codes D07 (console) CJ2 (electronic auto A/C controls). I'm getting all sorts of conflicting information from the various parts sites - Rock Auto seems to think that only the most expensive one they offer will fit ($260), while GM Parts Link says that the cheaper style will work.
The Auto Parts Warehouse site shows no less than three different styles alone for the front core. I have no idea which one to get.
Has anyone done this job on a truck similar to mine that can tell me 100% which one is actually in there? I'd hate to have to wait until I can get it all apart and find out, then wait another two weeks for the part to arrive. Would rather just order it all now.
e: Is there a way to look up the parts I need using the truck's VIN number / RPO codes? There's a website for BMW that lets you just type in the last 7 digits of the VIN number and it pulls up exactly the parts I need, not every single variation ever created in the chassis' history. Anything like that for GM?
e2: Looks like GM Parts Link lets you enter a VIN, but I'm still not sure I trust it. Would rather have some real-world experience on this one if anyone knows Thanks in advance all.
