Hey guys I havent posted in quite some time so looking for some insight. just the other day my meter fuse popped .so i change the fuse and immediately it pops again.I know that this is usually a sure fire sign of a short but i have no idea where to even begin looking for a short i have been having problems with my heater controls but as far as i know this isnt conected so any insight would be really helpful at this time

Probably a shorted reverse switch. Does it pop when going into reverse?

(common FC problem)

why would it pop doing that ?

wouldnt just your reverse light stay on ?

also Ive never been able to find any wiring diagram's refering to the reverse switch got any details ???

no real details it just started i didnt notice when exactly it done it the first time
and then when i changed the fuse it did it imediately upon start up im kind of lost.

It is a short to ground. Start unplugging each item in that circuit one by one and check voltage at the meter fuse after each item you unplug. Once the voltage goes away then you'll know where in that circuit to look for the short.

I would start with the reverse switch since the connector is fairly easy to get to and they fail somewhat often.

Another important question, does the fuse blow when the key is turned to acc or when the starter is cranking?
