Faulty throttle position sensor

I mworking on my blazer AC unit now . You have a problem with the compressor clutch or the compresser Its likely the clutch its supposed to cycle about 8 times per minute . So it goes on then off 8 times per munite this is normal . However if the clutch dosen't spin then the belt will drag on the clutch pulley this will stall the engine until the belt wares out but this will damage every part that the belt rides on . The water pump the alternator powersteering pump and belt tenisinor not to mention the belt .It sounds like your clutch is seized try not to run it until you can figure out why the clutch isn't spining

I would suspect you have a bad A/C compressor. When you engage the A/C, the clutch locks up the pulley which kills your motor from the drag on the belt. Replace the compressor, evaporator and valve, then recharge system to 55 psi.

I just did this on my 04 blazer. Remove the ashtray from the holder. There are 2 small scews in the corner of the ashtray (remove them) pull out the ashtray holder, it will only come out about 1 to 2 inches just enough to get your fingers behing the back of the holder. Here you have to removed the cig lighter connector then you could see the ashtray bulb holder, It is plastic so be careful. You have to push in and turn the buld holder. It only has 1 plastic tag on the side to hold it in place. Then you can remove the buld. It look like the old tail light buld fixtures with the slot on the side. Its easy to replace but a pain to get to.

ya go to a mech, if you strips the srews on the cap (and rotor), youll be sry. I have a blazer for 10 years and find that they must be changed yearly. Buy a GOOD set of plug wires and GOOD spark plugs, they are a real tought time to replace.

try idleing up alittle not power to keep it going

Could it be a starter? does the engine turn?

sounds as if you cut the wrong wire.... i would recommend taking the cd player out and trying to patch everything back up to original and maybe get someone to fit the cd player for you? hope this helps

It might be two different things. First have the ball-joints checked for the creaking. Also have the tire balanced checked for the vibration.

This sensor connects into your coolant hoses. It is usually close to where you put coolant in, close to the coolant cap.

a vacuum leak could cause this. dirty air filter. worn out plugs dirty fuel filter. the codes dont necessarily mean the o2 sensors are bad just that a condition exists. lean/rich that the o2 sensors are picking up. examine these items to see they are clean and in good working order. hope this helps

ita all electronic

The blinking is a trouble code, a qualified Tech with a good scanner should be able to pinpoint the problem. There are many components in this system, trying to replace them on guesses can get very expensive fast.

Hi, TRhe fuel pump is located in the gas tank. Please see the attached for the specifics relating to your vehicle:

Good Luck!

Its on the intake manifold in the front left of the EGR valve derictly below the thermostat where the upper hose from the radiator connects to the engine in front.

broken 4WD shift linkage 2. hubs not locked

If the heater core has gone out you'll know it because it'll be leaking inside and you can smell it. Check the heater hoses and make sure they are both warm (which means the hot water is circulating). If not, I'd think the heater control valve is stuck. If it is, then I'd check to make sure the vent doors are working correctly. They are usually vacuum actuated. Are all the vents blowing according to the setting on the a/c control panel?

Very straight forward oin this vehicle-2 bolts.you may also want to backflush the heater core as this likes to plug.Make sure not to get to much water by the distributor as this will cause a running rough concern.

is it coolant leaking underneath and what side is it leaking from driver or passanger close to the firewall or close to the radiator.
