I have a suggestion. You might want to check your vacuum hose, and vacuum switch. My 4WD was inoperable. If you don't use your 4wd enough you can get dry rought on the hose. That may need to be placed, or check your vacuum switch which is located on the driver side in the transfer case. Might need relplaced, or take it off, clean it reteflon it, and tighten in back down. As for the clunking Might want to check it out at a Transmission shop.
my Chevy blazer power seat on my 1996 Chevy blazer isn't working
It sounds like a universal joint to me, it's an easy repair and cheap too.
If the overhead temperature module on a 1998 Chevy Blazer 4x4 stops working and the fuses are good, check to make sure the temperature gauge itself is not damaged. This is located in the front bumper of the vehicle closest to the front passenger tire.
check ground first
Either the arm on the actuator broke off (common problem) or the actuator itself burned out (which happens over time).
replace the spark plug wires
you have an AC leak
one of the lights is not working
you may have a vacuum leak somewhere.
if the 4x4 isn't working then you need to check your transfer case. is it making any noises? or did it just stop working?
what you working on? If it's a s-blazer i think i have the answer.
Could be a blown fuse.
Check the fuse, then the bulbs, then the brake light switch.
You could have a starved CV joint. Take your blazer to a wide-open space (i.e., vacant parking lot) roll your windows down and turn the vehicle in tight circles in both directions. If the noise is present have a mechanic check your CV boots/joints.
If nothing on the dash (instrument cluster) is working, I would suspect the electrical plug in back is disconnected.
If your brakes are locking up it is because the ABS is not working.
A blown fuse is the most common cause for the 1996 Chevrolet Blazer sheet and air conditioning not working. The fuse box can be found in the engine compartment.
Control problem, blend door not working are the places to start
Check bulbs, fuses, and check for wiring problems
There is a tag in the drivers door that shows the correct tire size for the car you are working on
Have you checked that the headlight switch is working properly?
Be sure the dash illumination dimmer switch is not turned off.
It would depend on what year full size Chevys you are working with.
