#568 of 607 4x4 not working by nickyp1

Jan 22, 2011 (3:12 pm)

I have a 1998 chevy blazer all of a sudden my I cant get my 4x4 to engage, when I press the button 4 hi or 4 lo it lights up and I hear it clicking on. I have checked all the obvious fuses and I am getting voltage to the transfer case. At this point I am inclined to believe that there is a vacuum leak or disconnected hose somewhere because at the same time that this problem occurred, my heater slide control will only blow out of the vents no matter where I position the slide control

#570 of 607 99 Blazer....many strange problems...PLEASE ASSIST by mthomasc

I purchased this a while ago and the vehicle was awesome. I started having issues with the vehicle not turning over. Ignition lights would come on, but not turn over. I replaced the starter three times before I figured out it was an issue with the remote starting system. Now if I try to start the truck with the key and it doesn't turn over I have to try to start it with the remote start system, using the FOB... which never did work from the day I bought the vehicle. Once I've tried to to start the truck with the remote start system, using the FOB, I would push the button on the FOB again... assuming this deactivates the remote start system. then I can start the truck using the key in the ignition....... strange. after this happened I no longer have the zones working for the heater/air conditioner.... vents only. no power mirrors, trying to engage 4x4 doesn't work. I hear a click and the light changes when hitting the button but it doesn't engage the 4x4. also the ABS seems to engage every time I push the brakes to stop the vehicle.

did you ever get this problem resolved? i know that we are having the same problem with our's. The 4 wheel drive lights up, and you can here clicking, and then the blower acts like it doesn't want to work properly. i know we also have a p0452 code comming up which shows a vacuum leak somewhere. i know i'm taking it to a mechanic in the morning to see if they can fix it.... please let me know if you found out what the problem was on yours

#572 of 607 Battery terminal melted by nljewell

Jun 09, 2011 (5:14 pm)

I've got an 89 Silverado with close to 200k miles on her, my problem is that the negative terminal melted when I was putting in a new battery. About a week ago it wouldn't start so I had the starter tested and it was good so I checked my battery terminals and I noticed that my positive terminal was stripped out. The parts store gave me a new battery, I hooked the + up first and when I was doing the - terminal I heard some sparks and then the whole damn thing melted. I am thinking there is a short somewhere but not sure where to start looking. Any suggestions would be great, like I said its got close to 200k miles so I am hoping it will be a cheap fix.

I not a guru on vehicles but I am cheap when it comes to car repairs. I would take every fuse out of the vehicle and and check continuity from neg to positive leads and start putting fuses in one by one. Sounds like you have a dead short. If you find a short with all the fuses out disconnect the voltage regulator and see if the short goes away. Chafe wire on a harness to ground!!!! Let your ohms meter be your friend. Good luck

Really?!
 
Wow, that's no harness issue I don't think...sounds like the positive battery cable is shorting out to the frame. You'd best follow it down to the starter motor and see what's up.
 
OR --- it could have been a bum battery from the get-go (internal short)...if you got it from a chain store, that could be the case.

#575 of 607 Blazer elec. issue? by shaner63

Jun 12, 2011 (10:37 am)

So my daughter's driving to work and the blazer just dies. I've got it home and I'm not hearing the fuel pump, AND I am not getting spark at the coil wire. The gas gauge reads empty, but it read a quarter tank when she left. (had went about 7 miles when it died) One thing she said was the speedo went to zero instantly when it died and while it was still moving. Dont know if thats noteworthy or not, if it would normally work with the engine not running. Kinda sounded like a major electrical issue to me. So I'm wondering would there be anything that would shut down those two systems (fuel pump/ignition) simultaneously? Seems like quite a coincidence, no spark and a silent fuel pump at the same time.

The same thing happened to me!!! The problem wound up being a bad battery put in a new battery and never had the problem again. Good Luck

Ok, so there is no fuse box under the hood on the 97 Jimmy, so where is the fuse for the O2 sensors? Started smelling gas, friend had a reader said I had no power to any of my sensors.
