Well, Tuesday of last week my wife and I get in the truck and get on the freeway (about 1 mile from when we started it) and after getting on the freeway I notice that the A/C wasn't working. A/C light is on, but hot air coming out. Then I try to open a window (due to it being like 115 degrees in the truck) and the windows won't go down. Look at the radio, radio won't come on. Then when I look at the Speedo, I notice that all the gauges are dead, no reading from any of them.

Crap, musta blown a fuse or something. We were heading to a Doctors appt for the wife, so I drop her off and stay in the parking lot to check fuses. I find that a fuse is blown (I believe it was #21, or whichever is for "Accessories". So on the way home, I stop by the local Auto Zone and pick up a pack of mini-fuses. I pop in a new fuse, and within 2 seconds it blows again. Darn, now what could it be?

So later that night (after the sun went down) I crawl back under the dash and start checking all the fuses. All are good, so I start checking the relays that are in the fuse panel. The truck starts, so I knew that the relay for the starter worked.
So I swap that one for another relay, and tried to start it, no start. Bingo, I found the problem, a toasted relay (Another "Accessory" label). No biggie, I'll even buy the relay to keep from going to the dealer and being without a truck for a couple of days while they are "fixing" it. I buy a relay the next day and pop it in. Everything works. Nice, I am back on the road for $8. Wife takes the truck to work the next morning, everything fine. When we go to lunch, the A/C doesn't work again, radio gone, windows stuck, gauges dead.

So, I took it to the dealer the next morning and told them what I did, and what keeps happening. Something keeps blowing the fuse, and toasting the relay (I don't know which goes first).

The only thing I have done is replace the door speakers. And when I replaced the relay, the radio works fine, no shorted speaker wires or anything.

When I dropped it off to the dealer, I told them I wanted the front-end shimmy fixed, the rear-end grind fixed, and the outside temp reading fixed.

 

Don't forget to get the muffler bearings repacked.

 

No kidding. But has anyone else had electrical problems like this?

 

All kidding aside, this is the first time I've read anything like yours. It sounds like there's a short or a loose ground somewhere. Good luck with it and hopefully the dealer will look into the other problems as well.
