    Default Rear window or tailgate leak in 2000 S10 blazer

    This is the year of the leak. First our suburban, now my daughter's S10 blazer. The carpet in the back is wet after our last rain. It's a 2 door and is 2wd, so no spare tire rack issue on the back that could be leaking. Anybody experience this before and have any pointers of where to look first? Thanks!

    Oh, yes. My '99 Burb had the wet carpet issue. I replaced the barn door gaskets with the LMCtruck.com set. Still wet. Turned out to be debris clogging the drain holes under the rear air vents back of the rear windows, over the tail lights.

    You may want to check the third brake light if it has one. I have seen the gaskets go bad and cause a leak.

    Good thought Pikey. I'll be sure to check that out.

    I had a 2000 S10 Blazer a few months back I was trying to flip that had the same issue, ended up being both the the third brake light and all the seals on the top and bottom gates.
    LMC had all the parts to repair and it only took an afternoon.
