when I lose all computer numbers I hear a "clunk" like im changing gears.

My son's truck had 3 of 4 of the door handles malfunction within 2 years of owing the vehicle, he bought used, but just thought it to be odd that the handles were malfunctioning

My passenger side a/c blowers cold but driver side is hot even with setting as low as it will go 60

I have a link to my video of what my truck does when I start it. I don't think it is the gauge cluster, I think something is shorting, and causing the dash to get power, then stop, then get power and then stop. The overhead seat belt warning light also flashes. The turn signals work, but sometimes the clicking of the flasher doesn't sound. This only happens for about 3 - 4 minutes and then the rest of the day the truck works fine no matter how many times you start it. Go to you tube and type in 2009 Chevy Silverado Dash Lights. Let me know what you think. Battery and both battery cables have been replaced with new.

Truck does not start in A.M. without jumping it. Starts fine the rest of the day. With ALL systems turned off, something is drawing over 700 amps from the battery. What is drawing the amps?

We are not sure what the problem is, when we got it bluetooth didn't work and no sound coming from speakers, radio worked and that was it. Dealer fixed it and now today ontop of yesterdays voltage dropping, radio on its' own switched to aux mode and wouldn't exit mode, even after turning radio off. About hour later, drove it again radio worked fine, have not had any issues with voltage dropping, but only been driving a mile or so today and everyother day. Except yesterday I drove it 2 hours out of town and back, afyer 20 minutes thats when voltage dropped and remained dropped. Also, I have no dash engine/problem lights. Was told my truck should have had a battery indicator light that was suppose to have triggered yesterday. Has not thrown any codes or any dash indicator lights. Any ideas what's wrong? It has fact dr34 alternator, was told to switch to dr44 and we think the ECM or BCM might be another problem.

after a few seconds sometimes the problem will clear & it runs ok again. sometimes you may have to cut ignition off to stop problem and it may or may not restart without a jump start & it runs ok until next time. has been to dealership, no trouble codes show up, no prolems found. HELP!

flash on & off,gauges jump up & down,engine starts bucking like its being turned on & off. after a few seconds all this goes away and its ok until it happens again. dealer has checked it,no codes show up, no problems found.help!

The ignition key cylinder is froze up and the key wont turn. I cant get it to the start position to release the key cylinder to change it out. Possible that when I parked the wheels were to the right so it may be stering wheel pin didnt disengage ? because the stering wheel is not locked. I dont know if my truck yr/model has stering lock feature or not. Ive tried jiggling stering wheel ..shifter..lil ele parts cleaner..lil w-d..lil vibration and holy water..lol. There is this theft deterrent device on the key cylinder..kinda looks like a door hanger lol..my question is..can a theft device like this cause the key not to turn mayb through magnets?..or chip in key bad signal? Thanks!

This module is around the key cylinder. Kinda like a door hanger lookin thing. Cant turn the key..can this device lock up that cylinder so it wont let you turn the key? I tried electrical cleaner, jigglin steering wheel, shifter..little w-d...new key. Nothing. Locked up tight.

My 2009 Silverado 1500 is only blowing Out of the defrost vents, no matter what the dial is selected at. I was told it was the actuator, but which one and where is it located?

I can walk away for awhile 2hrs or so and it comes right on.
