1990 GMC Suburban Wiring

I am writing for another person about this problem I just posted and you gave us a clue....thanks....Yes we were pulling a flat bed trailer, loaded, any more ideas about where to look in that wiring...are you saying it would likely be coming from the trailer wiring???? The trailer has electric brakes but they are not hooked up.

My 1990 Suburban needs new wipers, I bought the blades, however I dont know how to remove the old ones because it seems to have a different set up. you cant find just blades anymore it comes with the...


The 1990 Chevrolet Suburban has the most common hook-end wiper arms. Locate and press the tab or button where the wiper blade is inserted into the hook of the wiper arm and pull wiper blade out of hook. You may have to rotate and flex the blade to make enough clearance for the hook to pass through.

Hi, if the extra wire goes to the alternator, then yes, it goes on the big post along with the battery wire. This is your charge wire. Please let me know if you have more questions, and thanks for using FixYa.

Why does my 1990 suburban keep randomly blowing the ecm b fuse has gone months with out a problem then is drivible again then will blow fuses again. Seems to come and go on its own


Scroll up and LISTEN to the guy talking about a SHORT. That's what it is. Take off the air cleaner assembly. Lift all the wires up and off the engine, pull the big wire loom a half inch out of the hole it disappears in going through the firewall. Keep doing this until the fuse stops blowing. Took me ten seconds. I still don;t know which wire it is, but I am buying some rubber fuel line and/or wiring loom protector to insulate everything off the valve covers, etc. Be sure to pick up extra 15 amp fuses in case it happens again, and be ready to tell anyone who drives the thing what to do.

Case: 1990 GMC 1500 SLE Suburban. Ran just fine, then the ignition shut off when I hit a random bump or pothole. Cost me a $750 tow before I got on here and did the wiggle test. The fuse stopped blowing. I will update if my fuel line/insulation idea didn't work, but I think it will. I will also tape every exposed wire with electricians tape. . .

1997 GMC Suburban seat belt is stuck and won't come out


You must replace the defective seatbelt.
Although sometimes you can get them to come out by pulling VERY slowely, however this condition will remain in most all cases.
