#345 of 609 electrical problems
Nov 24, 2008 (7:43 pm)
I have a 1998 Chevy Blazer. First the windshield wipers were acting funny, they sometimes wont stop after I turn them on. Then the blinker on the right side keeps acting like it is on intermittently. Then the dome lights quit working and now the light that lights up where you push the button to put it into 4WD or 2WD is not working, and so it is stuck in 2WD. I need 4WD because it gets very icy and snowy here in Wyoming. Can all these things be related? A friend tried a new cylinoid and a new computer box, but still no luck. Please help me!!

calm down, fellas. Lots of us were travelling.
Okay, lets break this down. Wipers won't turn off, turn signal issue. Probably a bad multifunction switch there on the column. There have also been issues with wipers in the past where the solder joint of the connector on the circuit board of the wiper motor assembly cracks. You unplug the harness, remove the cover, and check the connector for cracked joints. Clean, resolder, reassemble. Don't need to replace the board, it will work when resoldered. Done lots of these.
Dome lights. Does anything turn them on? Any door, or the switch on the instrument panel?
The 2WD/4WD issue can be a bad solenoid at the transfer case, or a bad vacuum line. Others with 4WD have seen this issue, try searching for it.
Hazard and brake lights are on the same circuit, at least partially. Both go through the flasher unit behind the dash, and guess what, they also go through that little multifunction switch mentioned earlier.
So, it sounds like most of your problems are related to the servo engagement circuit for the 4WD, and the multifunction switch in the steering column. There is a detailed procedure on changing the switch on the previous page.
Hope that helps.

#350 of 609 Similar issue?
Dec 05, 2008 (7:49 pm)
Hi all -- I have an '02 Blazer. The top LED brake light the left rear brake light are not working, but turn signals and hazards work fine....could this also be related to a bad multi function switch I'm reading about here or is there anything else that someone has heard of that might fix this.....open to any and all suggestions. Thanks
#351 of 609 2005 gmc jimmy battery runs down
Dec 17, 2008 (10:24 am)
This one really puzzles me. While driving and once while parked, no keys in ignition. The interior lights come on and shut off by themselves. If I park the jimmy for a couple of days the battery runs down flat. I had the dealer try to find the problem on three different occasions. They said the battery is ok and they could not find a parasitic load. I am really puzzled on this one searching for answers.
#352 of 609 Parasitic drain
Dec 17, 2008 (11:23 am)
It may be:
There is a intermitten short causing a batttery drain. When the battery was checked for a battery drain, the short was not present. My 1991 Blazer had a battery drain and it was found to be a bad power door lock relay. The bad relay completely discharged the battery after I did not drive the vehicle for five days. Bad relays are common causes of battery drains.
The on/off- dome light dimmer switch..
The door switches.
They are inexpensive. See if doing that solves the problem.

I have a 1998 Jimmy 4x4 its not the battery its my electrical system but l dont know where or what. My lights act funny, one power window gets stuck sometimes, wipers change their own pace, the power reves up my engine sometimes, and my truck died at a light the other night and l couldnt get my speed up to more than 20mph so got it home and havent moved it since. lt starts up just fine but doesnt like to drive anywhere with gasping. lm taking it to the mechanic of course but l wanted to know if anyone else had these problems its never happened before.
#354 of 609 Wiper only works on High
Jan 01, 2009 (4:51 pm)
Would someone help me in understanding how my wipers work only on High? Everything else on the multifunction switch works... I already plugged in a new wiper motor (which includes circuit board). Do I need a new multifunction switch and if so, are they somewhat easy to install?
I have a 1998 Chevy blazer.
Thanks for the help..
