Have you had an intake manifold gasket job done recently? I just did mine and now my lights stay on and i can't rev over 2500 rpms.

 

Yep, you are right both switches on the two driver side doors are now disconnected and that problem is solved. One was broken and the other was corroded where the wires attach. Radio clock still always tells me what time it is maybe that is by design?. Now gotta do some research here on the Right Front hub bearing assembly.

 

What year is your Blazer? The only time my clock lights up is with key in ACC or on/run position. My weak battery won't last long that way.

 

It a 96.

 

Strange. Mine is 96 also.

 

I believe it was SoullessN who said she had to slam the door to get it to shut. I had the same problem on my 2001 Blazer Trailblazer. It got so bad I had to have the hinges fixed. But to anyone having a door sagging problem, I found quick and easy fix for $20. After a lot of googling I found a site called shimeze where you get these inserts that fix the door. You can even watch an install video on YouTube. It is beyond easy. But if your door gets too fargone you can't use the shimezes. Sounds like your door could use just a shimeze. Thanks for this post though, I have the same dome light problem. My door sagged and I had to shut it hard, then the bushings broke apart. Then the locking mechanism broke. It was a mess and ended up being a $200 fix. SO be careful and if you can get the shimeze. Trust me, don't let the sagging door go to long. I have to fix the locking mechanism now and possibly the sensor or something to make my dome light work properly....

 

Slamming the door Soulless made my truck way worse. Then lots of other things stgarted breaking. You don't have to replace the hinges at all. I found a $20 fix online that works. You can watch a video on YouTube [ ]. I let mine go too long then it became a $200 fix just to correct the hinges. http://shimeze.com/ You might find your luck here. I hope this helps. I'd hate to see other people have more break for not knowing this. I swear by it now. We're going to use these on my other blazer, a 1999 2door 2wd.

 

01TrailBlaze,

I think this video would be useful under a special thread for known specific problems like this. Fortunately for me, I am subscribed to this thread and coincidentally I have a door just like this I need to fix.

My door sags because bushings/grommets (?) on the hinge have broken off. Was this the reason your door was sagging?

 

 

I've had mysterious lights staying on too. The fix was the diode in the alternator was bad, lets current bleed thru.
