Please help it's a challenge working out of this truck in one hundred degree heat..ANY info greatly appreciated
I lost my power brakes and power steering why would that happen
my daughter has a 2000 gmc sierra 1500 4.8 ltr 4x4 . at first start up engine has a knock sound for 2-3 min then is gone for the day. No check engine light visible doesnt burn oil tune up piugs/wires with in 3 mos. . sounds lower end noise not top end. what do i check and how. is it a knock sensor possibly?
While driving down the road, once i get to about 58 mph my truck will start shaking. It increasingly gets worse up until about 70 mpg it dies down. Around 62- 63 is definitley the worse. I just got brand new tires, replaced the pitman and idler arm, its been alligned, i dont know what else to do with it.
Ruled out engine, no oil pressure change. My dad raised the tail of tranny near u-joint to remove pan. Could this be cause of knocking I have noticed recently? Knocks all gears, louder in park or neutral.
door window passenger side will not go down
After my engine has been running for a mile it will slows down and over heats a little and feels like the engine is not getting enough fuel but got my fuel pump checked and it is fine. I have replaced the throttle sensor and fuel pressure sensor and still nothing. Any suggestions? Weird thing is that the check engine light won't turn on not even when you turn the key before starting the engine.
Problem started after the trucks battery and fuel pump messed uP 4 days ago. Fuel pump replaced and we got a new battery The same day. Basically we have to continuously flick the turn signal/hazard button off and on in order to make the light appear to be flashing. We didn't have any lights at first and before the lights died the blinker was making a weird noise while just barley flashing. I got a new relay And that got the lights on and got rid of the noise but they don't blink. Not sure where to go from here.
drivers side leak under dash
Sometimes when I start my truck and put it into gear it won't move like it is in neutral. When it does this i noticed that the service 4x4 warning is on and the push button 4 wheel drive selector on the left side of the dash displays the red neutral light. After I shut it off and try again it will start working. I have been having problems with this push button switch in the past but I don't know if it is the switch or something else. Thanks
195000 miles on it.
Air only blows out of defrost vents (not dash vents). Air currently only blows hot regardless of temp setting or if a/c is on.
Passenger window will not roll down.
Code reader also does not work. Is there a possible fuse problem as well?
