Have a OBII scan (fault scan) done any good shop or parts store can do it.(Most will do it free) Just because light is not on doesn't mean there's a fault. You computer tracks literally everything. I'm suspecting crankshaft trigger but have the scan done instead of throwing parts & $$$ at it.

2006 Chevy Trailblazer - Hit a small bump in the road and the ABS light comes, Traction control light and then it goes into power down mode. Had a scan done on it at a local parts store and they said is...

More than likely one of the wheel speed sensors was damaged or its connector was jarred loose. The ABS control module is the heart of the ABS system and rarely goes bad. Suggest you take it to a mechanic that is familiar with the Trailblazer and have a diagnostic done.

Trail blazers are known to have coil packs go bad, and you will loose spark on a cylinder. I would first get the check engine light scanned to see what the computer found. The etc fuse may have gone bad due to a wheel sensor issue, but, get the check engine light looked at first.

Runs Ok...engine warmed up...come to red light or stop and RPM starts going up and down, oil pressure drops, check gauges light comes read out low oil pressure..stop engine. Some times goes...

Sounds to me like the Throttle Position Sensor. Thats usually what makes the throttle "rev" But that is not going to make the oil pressure drop. Pull the codes from your car and look them up online. sometimes there is an extra fuse u can add to your panel and turn the key on and it will flash your codes via the check engine light. i.e. if the light flashes 2 times then small pause then 1 time and long pause that is code 21. if there isnt a extra fuse you can usually jump it with a paperclip and pull the codes. not really sure how to do that with yours. but im positive Google knows ;)

2002 Trailblazer LTZ Passenger window comes down by itself !!!

Check the wire harness that leads from the door into the vehicle, possible wiring problem at that point, if all is good there, it may be the body control module. If the other "electrical problems" are component related, it could all lead to the module.

2002 Monte Carlo wont start

sounds like your passlock sensor on the ignition barrel is faulty. you will have to go to the dealer to have it replaced because of the programming after replacement.
