Check your intake manifold for a vacuum leak. Many older GMs used a vacuum actuator to control duct venting. Also check the vacuum actuator, I'd bet you have a leak somewhere, just find it, and fix or replace the leaking part. |

I just bought a 1998 Suburban yesterday. Very nice ride loaded 174,000 miles. I noticed one problem last night. When I open the doors I have no dome lights on the headliner but the lights on the doors all work except one. (Burned out I think haven't figured out how to change it yet.) Anyway I have tried pushing the dome light over ride button it does turn off the door lights but that is it. I took the cover off of the lights on the headliner bulbs are good tested the contacts with a multimeter. No power to the contacts. Not sure where to check next although all the fuses are good. Any ideas????

Replying to: steve_ (Dec 08, 2004 11:21 am) I have recently acquired an '88 GMC Suburban, who runs wonderfully, but be it 50 feet or 50 miles it eventually gets very weak, engine light pops on and bam she dies. I've changed plug wires, inline fuel filter, and am getting ready to change the distributor cap, but any suggestions as to what is causing this would be much appreciated as I'm beyond baffled at this point and ready to sell the thing for scrap!

I have a 95 GMC suburban. When I set at a light or behind a school bus my engine light comes on. I have been told that it is the idle is too high at the times. I have even kicked the engine down when stopped and it still happens. Could this be a short somewhere or is this just the start of a big problem to come? |

I have a 03 Surburban. When I press the 4WD button it blinks a few times and then goes off, same with the Auto and 4WD lo button. Any ideas? Thanks!
