I have a 98 Jimmy had the same problem. The problem is in the turn signal switch, small particles of metal (from the contact points) get mixed with the di-electric grease. You can either buy a new switch or remove the old switch and take it apart, clean-out the old grease then apply new di-electric grease. According to the repair manuals you have to pull the stearing wheel but I managed to remove steering column cover without removing the wheel just be careful.

I have a 98 Blazer with the same problem. It started with the clicking behind the glove box, then the cruise control stopped working, and now the windshield wiper works only when it wants to. Does it sound like cleaning out the di-electric grease and replacing it will fix these problems, or do you think I need to get a new switch? Is replacing the grease complicated?

I have a 98 Blazer, suddenly the speedometer/gauge lights, radio display light and compass/thermometer light are not working. Also, when I turn off the car and leave the headlight switch on, the audible notifier that your lights have been left on, does not make noise. I have tried the dimmer switch and is not helping...the light behind displaying what gear I am in, the tachometer and the 2WD indicator lights are the only ones that do work...any suggestions?

Sounds like a fuse. Open the drivers side door, and pull the panel off at the lower dash (push and turn knob). On the back side is a fuse map. Check for Inst pnl (instrument panel) and replace with the same size spade type fuse (should be spares attached to the cover).

It cut in and out a few times which leads me to believe it isn't a fuse, but I will certainly take a look and appreciate your advice. I looked at the fuse panel layout in the owner's manual when it happened and the instruments that are out seem to be on several different fuses, but again, I will take a look.

I would suspect the headlight switch assembly - its about $55 and after you pull the dash bezel off (center screw above gauges into dash top, recall 2 on the lower trim under steering wheel , then bezel snaps out and you change the switch by unscrewing 4 more screws) but watch out you do NOT break the hazard switch on top of the steering column when you remove the bezel! The dimmer section is a rheostat with a heat sink and they fail and then it has the auto headlight on/off feature in it too. Most auto stores carry these in stock.

Taking the switch out isn't hard as long as are careful, taking the switch apart isn't too bad but can be fun to put back together. Look at this way, you can try to fix the switch first, worst-case you will need to buy a new switch.

#24 of 607 Charging/electrical problem by dolphin1

Hi,
My 2000 Blazer started making an electrical whinning noise which corresponded to the rpm. Soon after the noise started, my original alternator died. I replaced it with a NAPA reman, and it worked fine for 3 days. On the forth day, it too died. I brought it back and got another one. After installing the second reman, the electrical winning sound returned and the voltage is fluctuating from 12.8~14.0 depending on the rpm. I have also recently replaced my battery with an Optima yellow top. Am I looking at some sort of short. Help!!

Get the system tested - free at most auto stores and it will do a load test and amp draw. I skip the rebuilts now due to the problems you have (or had) and for $15 more get the new one - about $150 vs $135. Could be the tensioner pullet or idler pulley or water pump so listen closely and get the free test and check the main cables too.

My jimmy wasn't working awhile back and to get it going we had to jump the relay. Now i when i turn on the right turn signal the fuse blows and when i touch the brake pedal the fuse blows, Also no 4 ways. I'am not good with electic wires,but i will try. Just not sure where to start looking.
