#342 of 607 Chevy Blazer Elerctrical Problem
Nov 03, 2008 (8:27 pm)
Hi all, I have a 2000 Chevy Blazer that suddenly died one night without warning. It was already parked for about 4 hours, and when my wife attempted to start it, nothing happened. At first we thought it was a dead battery since the security light was flashing, but nothing else worked. When we turned on the head lights or blew the horn, the security light would die out. Even after charging up this battery, replacing it with a new one, checking all of the fuses (they were all good), even had two mechanics run a tester on it, there is absolutely NO power running through the system. Sometimes when the hood is open the hood light will come on but as soon as ANYTHING else is engaged it will die out. Any ideas? This is "driving" me nuts.

It could be that your battery ground cable isn't working properly. You could check the connection at each end and possibly replace it.
#344 of 607 battery cables

I had engine miss under a slight load because of a weak ignition. I determined it was a loose positive battery cable end clamp.
Do not install those aftermarket end-clamps because they are just a temporary repair. If your AC Delco battery cable clamps are old or they are those aftermarket type clamps, replace them with new AC Delco side terminal battery cables and install a AC Delco 75-60 battery. A new AC Delco positive battery cable is somewhat difficult to replace if you want to route it the same way the original cable was routed. Unfortunately, that is about the only way you can route the positive battery cable in order to clear the exhaust system and attach it to the starter. .

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 607 Similar issue?
Dec 05, 2008 (8:49 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 607 2005 gmc jimmy battery runs down
Dec 17, 2008 (11:24 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.
