A couple quick questions regarding the #15-72267 AC controller used on the 1995 models vs. the #15-72548 used on the 96-98. Does the #15-72267 have similar problems and wiring to the #15-72548? Is it interchangeable?
I found this great How to on the site How To Repair GMC CK Series Trucks HVAC Control Unit and plan to use it to troubleshoot. My 95 suddenly stopped cooling and the AC light doesn't come on. Hoping the wiring diagram in the how to is close enough to find the problem.
I also plan to check the transistor mentioned in this article and wonder if it is the same on the 95. How to fix a 1996-2000 HVAC control module
Thanks in advance for any experience and expertise.
