OK this thread sounds like what I have to deal with. My 2007 Trail Blazer has started doing strange things with the fuel gauge. It will signal empty (low) when I have half a tank and will move 1/4 tank up or down in just a few blocks driving. Where do I find out about GM splitting the cost for...

Hey it may be something simple like a solder joint and I may tear into the module and see what it is made of!! In the meantime, I just decided to bite the bullet and get a new module. I found one on Amazon for $28 and change with free shipping so I ordered it. It came in a couple of days and...

Well so much for clean and reinsert the module. I took a drive and the signals worked for about five turns and then quit. Guess I am in the market for a flasher module. Hope that will cure the problem. John

Well OK, I roughed up the pins on the module and sprayed a bunch of CRC QD Electronic Contact cleaner in the plug holes. When I plugged the module back in the turn signal is now working. I am hoping that it was just a bad connection (and thus saves me a bunch of money LOL). Time will tell but...

Humm Roadie, I figured out a way to pull the module without breaking my back (I'm 79 and getting a bit stiff for this stuff) because I wanted to make sure that it did not have a bad (corroded) contact pins. The pins all look fine. Low and behold the module number is quite different from the...

Ah ha. Thanks Roadie, Now I'm wondering if I have the right part# for the unit. The one I have is GM 12450284. It is labeled 2/4-W/OPT Trailering and I do have the trailer package on my Trailblazer.

I know this is an old thread but I have the same problem. I wonder just what the lighting control module is?? Are we talking about the flasher?? Thanks

Dozer22, The fuse (which is called a circuit breaker on the wiring diagram) is under the rear seat. It is #9. John

Thanks Chuck, Testing the motor is the next thing on my list but Roadie in an earlier post says that the motor is shot in only about 10% of the dead rear wiper problems. In any case, if it is the motor gone south, I will probably hit the junk (oops I mean salvage) yard first for a replacement...

Thanks Roadie, I was able to download the "official" 2007 wiring diagram from this site and I will have to decipher it Am I correct that the motor will only run if it receives a proper signal on the speed control wire (line E which is dark green)??? It looks like the orange wire (C) should...

OK, I have exactly the same problem with the rear wiper (dead??). Fuse #9 is not blown and looking at the wires in the lift gate hinge boot does not show any that are broken. I guess the next move is to expose the wiper motor and put a meter on it. Anyone have hints as to how to get down to the...
