Howdy,
I've been driving a 2001 blazer since 2006... love the vehicle previous was a '93 blazer.
as can be imagined there are a few things going south.. drivers door is hanging a bit shuts hard (lift and shut) pin hole in hinge is rounded out.
Flasher unit is running even when not in use stops when brakes applied. combination unit (signal/4-way/cruise) switch needs to be replaced?
Lower sections of body mount bushings(rubber and cup) falling out, so I need to replace those.
I've seen how to replace the combo switch.. does that sound like it will fix that problem?
The body mount bushings looks like a pretty straight forward procedure...rubber or silicone?
The door hinge...? can you buy oversized bushings (O.D.) for a new pin?

 

Hi and Welcome!

I can't help with the specific questions. I'm sure someone else might be able to help.

 

Have you checked lmctruck.com or carparts.com?
If you need parts for door hinge.

You can always try ebay. My window got busted on my jimmy and I was able to order one from there. Glass shop was able to install it perfectly.

For the the flasher unit. You can replace the relay but if that don't work. May be a wiring issue. Keep us updated with your progress.
