I have an 88' Cherokee pioneer and after a rainstorm, i lost all of my lights except my turn signals, no headlights, dash lights, dome light, brake lights or hazards!! I have checked all the fuses and there are all good. any suggestions?

 

did u have ur window down so water could get in?

 

I have a leak in my windshield on the passenger side top corner. it dripped straight down onto the passenger floor and some may have dripped down the A arm into the dash.

 

do your highbeams work? check all the fuses but im gonna say headlight switch...

 

If it was just the headlights I would say switch also, but the brake lights and dome lights mean it is something else. Check the fusible links on the starter relay. Use a test light with a sharp point and pierce the wires down stream from the link.

 

Is your radio working? Will your lights come on momentarily if you pull the lever for high beams all the way in and hold it? Check the fuses... on my 96, the dome, taillights, and buzzer for the door are all run through the same 15A fuse. (It keeps blowing... looking for the cause)

 

no my high beams do not turn on momentarily if i hold the multifunction switch, i checked all fuses and replaced the headlight fuse just to be sure, also my radio works fine. I checked all fusible links and the all had power...bad ground somewhere maybe? or is there a module that may have fried?

 

im still saying either your headlight switch or turn signal switch. I had a vehicle that did this very same thing...turned out to be the T/S switch...either way you need to get in there with a test light.

 

i'll try the headlight switch first, the guy i bought it from recently replaced the t/s switch.

 

are you talking about the turn signal switch, or the multi-function switch? or are they the same thing?
