How can I stop the heat in the Driver seat from coming on every time I start the truck,

Engine light stays on

When I turn my truck on and start driving

i am having problems find it

i have abs lite and brake lite on dash, code reader says 0141 but mechanic says its my electronic brake control module which is up to $1000. to fix. and when i search i get o2 sensor for code 0141. i look under my truck for module and my gas tanks are there, i know there are several questions 1. what is wrong with my truck? 2. is this even possible for me to fix? and can i repair it myself as i see on you tube ? or do i have to soend the grand to have it fixed?

im hearing a sound like gears grinding together in the front of truck on drivers side, and i can hear that something is loose, i looked but didnt see anything wrong. but it sounds like clinging, like the wheel is loose ,and the grinding isnt constant if i stop it will stop but sometimes upon take off it starts grinding again. like some thing is loose or broken or trying to engage while driving. also having problems with 4 wheel drive .it says service four wheel drive in the instrument cluster could that be part of the problem or the whole problem?

i have troubleshot the starter, battery and ignition circuit, when i turn the key i get full power to all accessories, radio works and dash voltage meter reads 12vdc, sometimes when i wiggle the three wires (yellow, black and purple) it turns over, i have tried using a dielectric grease on that connection and it worked for about a week then started again.

Instrument pannel not functioning correctly.

When it rains or is high humidity my 4WD selector buttons/lights default to 4WD Low and won't change so I can't drive it to work or long distances. Can it be made to stay in 2WD all the time by deactivating it on the 4WD transfer case. It's liike there's a short somewhere in the actuator. I've only needed the 4WD twice in 10yrs.

noise appears to be coming from driveshaft

when i brake at a low speed i feel after i stop like a grinding in the pedal. i checked brake pads and there ok

It occurs every time I start my truck

Everything electrical on that door does not work

The lights used to be different everytime i started the truck. after backing out of the driveway, i put it in drive and when i took off it made a loud bang in the front axle/transfer case area. Now i have a banging noise sometimes when i turn or am on a tilted road. Ive heard to check the cross member but i think this is bigger than that.

Notice of "check Gas cap" came up dashboard Tuesday. Gas cap was tight. Repair shop Cleared code - light went out. On Wednesday check Eng light came on. Replaced Gas cap. Repair shop Cleared code again- light went out. On the way home light came back on again. Diagnostic meter says "Emission Sensor Valve" Both times -->i believe was the Code name when they told me to tighten and/or change the Gas Cap which neither worked. Any suggestions?? What & where is the Emission Sensor Valve??

Shortly after flushing out the radiator and replacing the fluid, i started hearing, what sounds like a fan running intermittently, while i'm driving. Could this be something I did wrong when flushing the radiator? any help would be greatly appreciated!

do I need to remove the pitman arm and the steering gear box together on a chevy 4 wd? it seems that there is not enough clearance to to detach the pitman arm from the gear box as it sits in the truck.

I have a 2004 Avalanche, it will automatically go into 4 wheel drive. I have had problems with it previously when putting it into 4-wheel drive and couldn't get out of 4 wheel drive. Finally, after getting it out, I took it to the shop and tey recalibrated the transfer case. Now it will go into 4 wheell drive automatically and the red light came on for the 4 wheel drive. What do you think the problem is? Thanks for your help.

Replaced both kock sensors a one year ago. Now having a problem with engine light coming on (knock sensor low voltage input) when I fill up at certain gas stations. Light stays on until next fill up, then goes out after a few miles on the new tank of gas.

Truck vibrates in front end at 70-75 miles per hour. Just driving does not vibrate when breaking. I have had the breaks checked and they are fine as well as had front aligned. What would cause this? Only vibrates it feels like in front end at this speed. I have had tires balanced and rotated.

The lights are coming but very dim. When I press the button to unlock or lock the truck, lights are fadingly dim and the horn sound sick in trying to sound off....when I turn the key in the ignition, its a little clicking noise...What could be the cause of this?
