Thread: 97-03 Need pics of dash off? Post before I get it back together

Some know the neighbor kids car smoked the DRL diode wiring.


Using the FSM's I'm not finding the splice where they say it should be. Having to go a bit deeper to fix a short somewhere in the dash.


You might ask..where's that last pic?






Anyone need any pics of stuff before it goes back together?

Holy cow!!!

Painful!!!

wire nest...i've only pulled one dash in my life...i swore i'd never do it again

since you're in that far, in your professional opinion bill.... how difficult would it be to take all the wiring out and swap it over to a different year. i have a 97 shell but i wanna run a 99 harness / ecm in it. the donor car is rotted out in the rear.

I wouldn't replace the interior harness in your car. Run the 99 under the hood. I did in my 97 Bonneville. The way I did it was to map the pinouts where the engine harness connected to the body. In the case of a GP, that is at the relay center IIRC. Map your 99 and a 97 both. Compare and move the few wires that are different. Use the circuit numbers for hints if things seem different, GM typically uses the same labeling on circuits.

Passenger bag is attached to the structure of the dash, not the pad. I didn't have to unhook either bag. If you do unhook a bag though..put your body down by the floor when unhooking. That way you can't get clipped and beaten by a bag. Pulling the dashpad off isn't bad at all.

Basically it was:
Pull lower panel under steering wheel, lower wheel (a few 7mm's and some 13mm's, no wire disconnection)
Pull glove box (7mm)
Pull radio, unbolt hvac (you can leave it hooked up), pull cluster, fog switch, headlight switch (plug back in to stop dinging)
Pull console (10mm electrical disconnect)
Pull ashtray (7mm and electrical)
Pop the switches to left of glove box for trunk etc
unbolt OBD2 connector (7mm)
Pull dash trim (turn light and sensor counter clock to disengage)
Unhook module at top passenger (under trim you just took off)
Pop the two a pillars
Remove 4 10mm from trim panel area
Remove a few more 7mm holding pad down lower
Put shifter in "1" and slide over off.

thanks bill, i was gonna run the whole 99 harness because i wanna put the digital heater in the 97 and it currently only has the 3 dials. not only that, i wanna run the 99 gtp dic as my 97 crapped out. maybe this isn't worth the headache?

I got a quick question for you. The last few days my heater has been blowing only slightly warm/cool air (heater core?) and now today the fan speeds don't work at all. Also when I turn the fan on the headlights shut off.
