I have an 08 Chevy Express Cargo Van. My issue is the power window switch on the driver's side. The wires were clipped when i got it. I put it back together and it was working fine. However, recently two of the crimp-on wire connectors failed. So I had four open wires: dark green, brown, light blue, and dark blue. At one point I accidentally touched two of the wrong wires together and smoke appeared, and, no more power. I don't have a circuit tester. Did I more likely fry the motor or the switch? I don't think it could be the fuse, because the passenger's side window is working fine, and according to the floor console fuse box, there is only 1 fuse for both windows.
Also, you'll see I used a blue butt splice wire connector. Would anyone recommend a standard twist-on wire connector instead? Thanks!

 

No. Applying 12V to a motor won't fry it. It will just make it run. Fuses are there precisely to prevent damage from shorts. More likely you just tripped a breaker.


Do not use marrettes/wire nuts on stranded wire.

It sounds like you desperately need wiring diagrams. Run out and get yourself a Hanes manual or search the internet.
