Hey. I've done my searching and couldn't really find anything that would directly relate to my few problems.

1. About a week ago, I replaced the power mirror switch because it was broken. Before I replaced it, it would move the driver mirror only (even when the little selector switch was in the driver, middle, and passenger position) and in only one direction: down. It would never move the passenger side mirror even if the switch was to the rightmost position. After replacing it with a new one, whenever I try to use it with the truck on, it blows a fuse. It never blew fuses before. When I try to use it with the truck off, it doesn't blow the fuse, but also doesn't move the mirror.

2. Also about a week ago, I realized I had the wiring and bulbs and everything for the fog lights. The only thing that wouldn't turn them on was an unplugged wiring harness from the switch behind the radio bezel. I plugged it in and it also blew a fuse when I tried to use them.

3. The cigarette lighter plug was never working and I knew the positive wire was unplugged from the back of it. So today, I plugged it in and as soon as I tested it to see if it was receiving any power, it blew a fuse.

These are the only electrical problems I know of right now. The DRL, headlamps, radio, dome light, etc. are all working properly. Anyone have any idea why these 3 things keep blowing fuses? Thanks.

 

Mirrors: One bad mirror? which one blows the fuse? Disconnect it and retry. It's likely the bad mirror blew out the old switch contacts, now the new contacts work and the bad mirror blows the fuse.

Same thing with the Fogs, unplug one lamp at a time to figure out which socket is bad.

Sounds like a bad cig lighter socket, very common and cheap to replace.

 

Mirror: Sometimes when I get it to work without blowing a fuse, it'll move the right side mirror perfectly: up, down, left, right but won't budge the left mirror. And other times, it'll blow the fuse just when I try to move either mirror, mainly the left one. But, even before I got the new switch, both mirrors would move in only 3 directions: down, left, right. Now the right mirror will move if I get it to work like I said. So, I know the right mirror's motor is just fine, it's just the left mirror that I don't know about.

Fog lights: I'll have to try that when I get the chance. Would it be possible to test the sockets with a power tester to see if they're getting power?

Cigarette lighter: I recently bought a new radio bezel which came with a cigarette lighter plug plus wires. If it is just a bad plug, it wouldn't hurt to try and see if this other one works, right? Thanks for the reply.
