97 F150 Wiring diagram/electrical issues
 

I'm new to the forum and look forward to digging through all of the info on here.
Here are my issues. I have a 97 F150 and have had an intermittent problem with the electrical system. If someone could direct me to a wiring diagram I would appreciate it (I tried to search it here without success).<O:p
Here's what's going on. Every now and then the power windows and wipers won't work. From what I can tell they are on separate circuits but it always seems to happen together. Once it happens I can turn the truck off and restart it and it usually clears up the problem. But some days (like today in the rain) it doesn't. Like I said if I notice one not working the other always checks bad as well but the wipers will come and go without the windows coming back online. I can hear what sounds like a relay click on the dash fuse panel and I know the windows are working again and then I hear the relay again and they don't work. Looking at the fuses I don't see that they have anything in common but I've never had one fail and the other keep working
Anyone with any thoughts on this would be appreciated.<O:pThanks,<O:pAl<O:p

What the power windows and wipers have in common is the GEM module. It's located under the dash towards the left side. It looks like a black box with lots of wires. Check that area out and see if you have any water damage. When it rains, do you notice any water under the dash? Sometimes the windshield leaks, and runs right down into the GEM module, corroding it and making it fail.

If you need a diagram, see if www.helminc.com has any in stock.
