Anywhere I can get wiring schematics for Escalade & Sierra Denali?

[demonte1997]

Looking to retrofit a 2002 Escalade HVAC control in my 2002 SD. The Esky one has auto feature so the wiring plug looks a little different. I have the pigtail from the Esky so I'm thinking it would be feasible to splice that plug into my truck's wiring. Would like to see a schematic from both trucks to confirm what is going on with each control unit.

 

Anyone know where I could find this info?

Thats nearly impossible. The 02 escy has the auto computer controlled climate. Yours is not. It will be an unbearable project.

Its completely possible. Ive seen it done. It is not cost or time effective. That is why i havent done it.

Ugh... so it's not really even worth doing?

 

Eh, I have enough nightmarish projects going on with my Regal so I don't need to eff up the HVAC on SD. Luckily, I bought the Esky CC for $10. Shouldn't be tough to flip it and make some $.

 

Thanks for the info. I'll look into it, but doesn't sound promising.

It requires more than the control head and plug. There sensor units have to be put somewhere, bcm programmed, and probably other stuff
