I've recently started to encounter some electrical gremlins and I know they can be difficult to nail down so as usual, I'm wondering if someone on here can help so that I can give my mechanic a better chance of nailing it down or better yet be able to correctly tell him where the problem most likely is.
The first issue was with my fog lights. They would both come on as normal but then after a few minutes they'd go out and wouldn't come back on until the next time I started the vehicle. Then the problem would just repeat itself. It's like a wire overheated causing it to trip a fuse but the fuse is still good. Now they won't come on at all.
The second issue is the windshield washer sprayer. When I push on the end of the turn signal arm to wash the windshield the wipers will do their sequence but no fluid comes out of the sprayers. I thought that the washer fluid pump might have gone bad and bought a new one but it didn't pump fluid through the lines either which tells me that it's not getting an electrical current. I've had someone at work test the pump outside of the vehicle to confirm that it works and also confirm that when installed in the truck the voltage to it is extremely low when I try to use it.
My questions are...Is it possible that those two components (fog lights and wiper fluid motor) are tied into the same harness or is it pure coincidence that they failed one right after the other?
Also, can anyone suggest where to start looking or perhaps have a good idea as to where the most likely point of failure is in the electrical "bowl of spaghetti" might be so that I can either fix it myself or at the very least save my mechanic some time in trying to pinpoint the weak spot(s)?
(cue broken record) Thanks in advance (again).
