Alright guys so I somehwhat recently acquired a 96 6.5 two door Tahoe. Anyhow everything seems to be working fine but the HVAC. There's this tangle of wires underneath the drivers side panel underneath the steering column thats hanging to the floorboard. I'm not sure what's going on here or what's OEM and what's not. If anybody could help me with what's wrong with my HVAC, what exactly this cluster of wires is or does, or could point me into how to solve this I'd certainly appreciate it

It says valet on this?

Remote start of some kind?

thats defiantly an alarm system or remote start and shouldnt have an affect on your h.v.a.c system. what kind of issues are you having?

I have no idea lol

No lights and nothing works. Flip all the knobs to no avail.

Have you tried pulling the unit out and testing it with a meter? Test the connectors that go into the back of it as well, check circuit resistance and resistance to ground may help find the problem

i agree pull the unit out and test it and also check for voltage going to the unit from the connectors on the truck when the key is on acc. and test the ground wire for continuity. if there is no voltage at the connector then test at the fuse to make sure that your getting voltage there

*edit* just found a p/n on the remote start bullshit. I believe its supposed to remote start and cool your truck And work as lock/unlock so IMA rip this ghetto shit out and see what's up then. My locks do funky stuff too when you out the key in the ignition.

Alright pulled that out. My locks are acting normal now. Still having issues with the Ac. My panel has power due to the back lights illuminating.

Cliff notes to the whole thread, Ac blower not blowing but i have power to the panel. What do I check now?

Check your ac resistor pack for power going to it, also check power and ground at the blower motor. If you have a power probe try giving the blower motor power and ground to see if it work.
