Was driving and when applied brake check gauges light came on and vehicle stopped. EMC1 fuse was blown. put new fuse in and placed vehicle in on position and it immediately blew again. There is a short to ground somewhere but unsure where. The computer is not waking up due to fuse blowing before it can. How do I get GM wiring schematics for this vehicle?
That fuse powers the pink wire that runs to the coil, injectors, and pcm.
If the short isn't obvious, I disconnect everything I can from the wire and then put in a fresh fuse. I turn the key on and check the fuse. If it blows, I know it's something I haven't disconnected or the wire itself. If it doesn't blow, I start reconnecting things one at a time untl the fuse blows again.

There is a short in the brake light wiring, that I guess you know, these types of problems have no common fix, each is different, did you add any wiring like for a trailer?

In the Fuse Relay Box under the Hood there is a Headlight Relay. Replace this Relay along with a New Fuse and it should work. Let me Know. Please Rate my Response, I need all the Help That I can Get! Thanks!

Update: I took the car to a mechanic that specializes in auto electrics and he found that the wire that goes to the back oxygen sensor had chaffed through over the transmission and was shorting out and blowing the fuse. He repaired it and the car runs beautifully.
SOURCE: Cooling Fan Fuse
Sounds like a short in the wiring, or a bad fan motor drawing too much current. Check the wiring for shorts, if none are found, replace the fan motor.
SOURCE: speedometer gauge/climate control lights dont work
Look for a dimmer wire,, sounds like your radio dont have the option for the car dimmer switch,,
the power for these lights run through the dimmer wire for the radio. ether its not hooked up or the radio dont have the option for it.
there is a way to bypass the radio dimmer option,, BUT you have to know what your doing or you could fry something.
look for Car Radio Illumination/dimmer Wire: should be Green.
