    Here we go! 99 GMC K2500 Suburban

    Hm. Probably going to jinx myself but, I have owned 11 gmt400 trucks over the years (currently own 3) and I have never replaced a window motor or regulator. Had 1 bad drivers side switch and that was it. Suppose I’ll just consider myself lucky so far

    Brake switch

    So I have been experiencing a weird drivability issue for the past year or so, mostly the torque converter locking and unlocking at random times while accelerating or cruising at speed. Thought it was a torque converter/trans issue figured I’d deal with it until I replace the power train in the...

    Escalade vcr

    There was A vcr along with a 12” cathode tube tv in the mark3 when I got it. By that point I only had 3 vhs tapes left, so my passengers watched the star wars trilogy(4-6 thx) for a few months before the tv got the axe.

    1998 Mark III Silverado!

    I miss my mark3 Tahoe. Still my favorite of all the 400s I have owned...I have the same mood light overhead console in my suburban now, as well as the mk3 wood center console... the power rear window in a pickup cab is one of the only options I haven’t had in a gmt400 truck, but I do have a rust...

    Lost all my coolant through this device. What is it?

    Leave the thermostat housing off and fill through radiator till the coolant is up to the top of the t-stat hole. This and one of the funnels that attach to the rad fill help tremendously when purging air

    The Custom Conversion Truck Thread

    Awesome. Does it work?..I have only seen one of these trucks with a functioning power roll down rear window. It’s on the list of things I want to do, but probably never will do on the Sierra.

    noticed that switch on the overhead console that says slider window... is that for the rear cab window by chance?

    '97 K1500 Suburban, Airbag Light

    You can check the airbag sensors. If they get crusty it will turn the light on. One is up front on the bottom of the radiator support and there is another one under the drivers seat (I have seen a few of those that pretty much disintegrated from being under damp carpet for awhile). There might...

    Blinker problems. Hazards flashing instead of blinker

    Mine did the same thing. Was the multi function switch (blinker/windshield washer/high beam/cruise control assembly) Beware aftermarket brands with these switches. I have used a couple different ones and none had the functionality of the original oem unit.

    Pre-Bent Brake Line Kit

    If you use the copper nickel lines you can easily bend them by hand. No need to pay for prebent ones. When replacing the long line that runs to the back axle I rolled the line out straight, cut it, put the nuts on, flared it and slid it down the frame making necessary bends as I went. Super easy

    98 Silverado RPMs randomly start jumping around, running horribly

    Might want to check the ignition switch, had a similar issue with the 2500. The key was worn out and would not engage the switch sometimes. Had to push the key in quite hard to get it to engage the switch. Occasionally it would disengage while driving, all the gauges will die/drop to the off...

    98 Silverado RPMs randomly start jumping around, running horribly

    Same thing happened on the limited not too long ago. Cap hada few years on it but not many miles, pulled it and it didn't look too bad, had good spark, so I put it back on and started diagnosing elsewhere. Had a Delphi pump on the shelf, did that and the fuel filter, ran great for a day or two...
