HID Fogs causing strange problems

[92__silverado]

So this week i installed my HID fogs from DDM. They work great are bright and were pretty easy to install.

Here are my issues, if i am sitting in the truck with it running, listening to the radio and turn the fog lights on the radio goes to static and power runs to the rear wiper enough to make it jump about an inch.

Turn them off and the static goes away. It's almost like a power surge goes through the truck and causes the issues. I did the 6 high mod at the same time and thought this could be causing trouble but after removing it the issue remains.

Do you guys think it could be a bad set of ballast? Maybe to much power running into the fog switch causing the rear wiper to jump?

Thanks for your help.

The rear-wiper thing is normal for some reason. I have no idea why, but everyone's seem to do that on certain models. I have never had a radio issue, but they are high-power ballasts and could theoretically cause electrical interference. I would try moving them as far from most wiring and electrical systems as you can and see if that helps. I don't think it's a bad ballast, but you may also want to get a relay harness if you don't have one. It will help isolate the circuit.

My rear wiper jumps also. No radio/static problems though.

Maybe my stock radio is starting to die, i have thought the FM reception was a bit weak lately. Guess it is time to replace it.

My Rear wiper does too, well on My 2001 Hoe it does.

i just noticed my rear wiper doing the same last night. First time that happened, or else, first time i noticed it happening. weird

mine does it as well on my 03, they say it can be fixed by regrounding the rear washer motor but its not that big a deal to me

Sounds like a bad ballast or bulb, try swapping ballast from other side and see if it still does it. The buzzing problem with the fogs happens sometimes when you mount the ballast on metal, I ziptied mine to existing loomed wiring. And the wiper thing like someone previously said is the fogs and rear wiper share the same ground i believe. Mine does it too. There is a write up here somewhere to fix that.

Do you think that could be my issue? Mine are zipped tied to metal on a small area I found above the fogs. I guess when it stops raining I will go out and try to move them and see what happens.

my ballasts are zip tied to the fog lights themselves. they aren't touching any metal, but the rear wiper still jumps or makes a sound everytime i turn them on. I did ziptie the wires against the metal, but that shouldnt be a problem. Anyways, not a big deal but weird

The wiper thing is completely different than having the buzzing issue when installing HID's. There's a writeup somewhere. The wiper thing did it to me even before I had the HID's in there. The fogs and wiper share same ground I believe thats why.

 

[polobuds]

right. mine doesnt buzz. i never noticed the wiper thing before but now i do. ill check the grounding thing if i remember, or if it stops raining. makes sense though if they share the same ground.

So i got a little time and went and cut my fog light ballast down, this cured the issue. I mounted them to some existing wire looms and it seems to be much better. It will still cut out some weak radio stations but not everything like before.

I still think I need to find a better spot and get a new head unit but i ran out of daylight for now.

Is the high 6 mod where the lows highs and fogs can all be on at one time and if so then where did you get it or how did you do it. any help would be great thanks

Cool. I figured moving them would help.

Add an extra ground wire from the black wire at one of the washer fluid pumps to the chassis. The rear wiper will stop jumping when you turn on the fog lights. There's a TSB on it.

I just took off my stock fog lights. I'd converted them to HID but they're just about the cheapest factory lights I've ever seen. I put on a pair of Hella 55W amber fog lights - huge difference (way better than the HIDs), but with the extra current draw my rear wiper started jumping again when I turn them on even with the extra ground wire. Oh well, at least I can see now.
