Horn relay and auto window open relay have no power, wipers dead, power windows dead. If I jump power to the relay feeds the wipers work, the passenger window works but the driver's window only goes up (no down). My wiring diagram does not show what switch powers the horn relay. All fuses seem to check out. Am I missing a fuse link somewhere?

 

what vehicle...look for blown fusable link near soleoid or batt connections...

 

2000 F250SD, I figured with the 100 fuses in the junction box fuseable links were a thing of the past, ha ha! Yes, I'll have to start stabbing some wires over at the solonoid relay on the fender. It is so damn tight over there, it just looks like a pain. The older vehicles were much easier to work on. Maybe I'll pull the battery and use a continuity tester instead of a test light. The Haynes manual I have has a bunch of diagrams, but not the circuit I need of course. No fusable links shown at all. The truck got me through 2 days of plowing however, kind of annoying with not being able to open the drivers window though. I guess it is better than not being able to close it!

 

Just pull on them, the bad one will stretch.

 

Nice! I usually figure out they stretch after I find the bad one using test equip! Did you change the differentials in that truck? Is that a manual trans? I am running the 5.4 std cab LB with the 5 speed. I get quite a bit of piston slap out of this engine. It has at least 90K on it.

Thanks.

 

Diffs yes. auto. I get some racket when first start but after 10 secs its gone 80,000 miles..

Did you find prob?

On edit Now that I look at it the gem module works all the things you said were bad...Check fuse to gem or it may be bad....or

 

Sounds like some nice work. All of the fuse links appear good. They are all tight and are delivering power to the truck. Relay 3 (Horn) and Relay 4 (One touch window) in the dashboard fuse box have no power, no wipers or key bell either. Maybe it is a GEM issue. I need to get a complete wiring diagram to continue it seems.
