What is this?
is it possible to make an interior of 95+ gm400 not to creak? Had the interior on my 91 square with only occasional creak from center console, while on 97 seems like everything is making some noise.
I have a 1993 Sierra 1500 SLE Extended Cab Short Bed RWD automatic and I need to replace the dash harness. My truck has the digital climate control, radio, and equalizer. If I'm looking for one on ebay or the junkyard what year of trucks should I be looking at and I'm assuming it needs to be a truck with digital controls also right? Are Silverado harnesses compatible? This is my first post so hello and thanks.
Yeah I guess I should of taken a closer look at the harness, to see what is separate from one another regarding the hvac ( I have a 3 relay pack btw). I'll inspect the hvac harness to see if it is still good. My cdm unit wasn't working for a few years before and I see mice chewed through the wires right where they come out of the unit (most likely why it stopped working lol) I'm gonna look for another one. Thanks for the insight, very much appreciated. So I guess it doesn't matter whether I get the harness out of a bare bones truck or one thats loaded. Does auto or manual truck make much of a difference?All GMT400 dash harnesses from 92 to 94 are fairly identical. The HVAC harness is separate from the dash harness so you can replace the dash harness and leave the HVAC system alone... Unless that IS the problem, in which case you can get the HVAC harness by itself. Whether you have (or want) a 3 or 4 speed system will determine what vehicles to pull from: 92-early 93 were 3-speed (3 relays and a single connector blower resistor pack), late 93 through 94 were 4-speed (4 relays and a TWO connector blower resistor pack). No change in blower motors. The 92 displays may or may not support 4-speed mode. 93-94 definitely do (and as an aside, also support 3-speed system harnesses).
The stereo system doesn't matter, as the EQ support is determined by your central unit (CDM), not the dash wiring. Just curious why you need to replace the wiring?
Interesting……Best I can recollect is the interior on my 91 creaked more than the interiors on my 96 and 97…….is it possible to make an interior of 95+ gm400 not to creak?

I had the whole interior out at one time on 91. No creaks when back together.Interesting……Best I can recollect is the interior on my 91 creaked more than the interiors on my 96 and 97…….
