I'd guess a wire is pinched somewhere, or a ground is loose, corroded etc.
Hmm. I guess a wire is pinched. Come on, you've gotta do better than that. I'll give you an educated guess..
From what you're saying.. One of your high beams don't work; you couldn't turn off your windshield wipers, so you turned off the headlights and the wipers turned off.. My best guess would be a "hot-to-hot short". This is best described as, "I honked the horn and my driver side windows goes up or down". You also said that your turn signals won't work either.
Let me straighten this out in my head.
-Combo Light Switch turns on the headlights
-Pull the switch forward and the high beams turn on but there's no light coming from the low beams and high beams
-Turn signals don't work either
Now according to the wiring diagram, the Combo Light Switch is hot at all times. Meaning there's power to it. So that means that the switch selects the wire that gets power and sends the power to the relay. From there, the relay will pass on the power to either the low beams, high beams, or turn signals. From there the wire grounds out the circuit and it is completed.
Well since everything else seems to work except for the high beams. I can pretty much see that the Under-Dash Fuse/Relay Box for the headlight circuit is in essence, faulty.
This is what I think is happening. Everything works fine, but once you turn on the high beams, everything goes dead. This is because there's either a grounded circuit in the relay, or a open circuit in the relay. I believe that by turning on the high beams, the relay some how connected all the wires to the high beam wires. Then from there, the wire probably grounded somewhere.
That's my best guess so far. But if I had the car right here in my driveway, I can test the relay and the whole circuit. I'd tell you how, but then I'd have to write a book. So if you've got any questions, let me know..
have you seen this relay i just want to know what color it is? and thank you for the educated answed thank you to both of you for the help i have posted this a couple of time and no luck
PnX-R, the condescending attitude is not appreciated. I did a search, you've used the word "bubba" in five different threads. Cool it. Feel free to help people out but if you don't have something nice to say, then don't say anything.
This is gonna sound weird, but my buddies lude got all freaked out by having the wrong bulb in the tail lights. Check all the bulbs, but recheck the wiring, and see if you can find ANYTHING that look out of place.
Ok, I think I've got it. I just learned something new and I believe that the problem to you headlights is that there's excessive resistance. After playing with a headlight circuit board, I discovered that if there's no Ground to the low beam, it won't light up. And I turned on the High beam, it was a little dimmer than the other. So this is what I'm guessing.
According to the wiring diagram, the Low and High beam bulbs share the same Ground on each side. So if the Ground wire is corrodded, loose, or etc, it'll cause the Low beam not to light up. And with that, it'll cause the High beam to light up dimmer than usual. This is because of excessive resistance. The current going through the High beam bulb will look for Ground, and since there's no ground, it'll go through the Low beam's bulb back to the relay and find a ground.
Does that make any sense?.. Hope so. If not, let me know..
Oh.. And to the moderator.. In the Automotive World, there's only two techs. One is Bubba. He/she will keep replacing things until it works. The other is a Tech.. He/she will look at the problem and take an analytical approach..
So when I refer to something as being Bubba, it means don't do it.
Prime example of Bubba at work..
Hmm.. I keep blowing a fuse.. Why don't I try another fuse. Hmm, blown again?.. Try a bigger fuse.. Still doesn't work. Let's check the Starter.. Oh, and the Tire Pressure too..
hey just wondering were that circut board is? and thank you for all your help
Go to the Library and look in Mitchell and find it.
nevermind i figured it out. I just didnt put the terms together.
I just unbolted the ground circut box and noticed thier was some water in thier "not a big deal" but what i found was the paint was actually making not be able to get metal to metal contact.
Not only were my light screwed up because of this but my idle was low and my blinkers were haywire and my wipers you think they would have used seperate grounds for all of these. But oh well all fixed now
