Accidently wired something up wrong while installing aftermarket guages and I fried something under the dash I think because even though it blew a fuse for the guage lights..........I replaced the fuse and the guages still don't work. Any ideas? What else shoudl I check if its not the fuse?

 

Have you check the gauge bulbs ? You may have fried them.
Also double check that it's the right fuse you changed. Check to make sure all your fuses are OK. Drop in another fuse in case that one is bad.
Check that power is getting to the gauge lights with a voltmeter.

You may have also damamged the dimmer control module, located below the radio in the dash.

 

Dimmer module under the radio? Maybe that's my problem. Mine haven't worked for a very, very long time.

How do I check it and what does it look like?
