Replacing The Head Gasket

The blower motor resistor is located in the same duct that the blower motor blows through. If you see the blower motor, within a foot of it is the resistor. The blower motor actually blows over the resistor to keep it cool. The blower motor is usually only in 1 of 2 different locations. On passenger side, access under the hood or under dash access behind glovebox. In both cases the resitor will be in the duct that the blower motor blows through.

The problem will be some where between the road wheels and the suspension mounts on the chassis. Here's a check list to try. -Wheel rims. Balanced doesn't mean straight. -Loose wheel bolts. -Brake discs for warping, Pads for wear and calipers for sticky pistons or loose fit -Hubs and bearings for wear. -Ball joints for wear. -Suspension mounts, top and bottom. -Suspension swing arms at both ends. Do this for the front AND the rear of the car. If none of these are the issue you might have to get the drive shafts and transmission checked.

Sounds like a blown globe check the globe on the blinker that is not working it will probably be black or if you have good eyes you may see that the little wires that connect the two little prongs inside the globe are broken. Hard to see so as they are only a couple of dollars best just replace the globe on the one that is not working. To access you may need a Philips head screw driver to take the cover off. Or it may require the globe case may need to be turned from the inside. If you are not shore how to get it of take it to a place like a auto shop they will probably change it for you This is most likely the problem. Let me know if this fixes it. Regards Craig

check relay in your electrical box on the drivers side under the hood

rear of the engine

Probably something wearing out back there.

i had a faulty speedometer unit on mine replaced and all was fine

There is a door inside your dash that switches from heat to defrost when you operate the dash control, it is not working. Could be as simple as a bad vacuum hose. You are lucky it is on defrost since it is close to winter.

Is it hooked up right ! Have seen wires reversed causing same problem !

You need repair manual if you think it is relay. Could be fuse, could be switch. http://www.manualslib.com/

The engine computer must see oil pressure or engine RPM to turn the pump relay on. Otherwise you only get power from the relay when the key switch is first turned on. You could try to bypass the pump relay to see if the engine will run.

This is common, the pump will run for 3 seconds when key is turned to the "on" position to prime the fuel system, then it will be turned on by the ECU when the engine is started by a signal from the crank sensor.

I would not think a fuse would be the problem. A fuse either blows or it is good. The relay might be at fault, but I would think it is the pump going bad.

a worn key, worn key tumbler or damaged key switch. it will need to be replaced.

It sounds like you have a defective alternator. The diode in the alternator my be bad and therefore not charging the battery. Have your mechanic test the alternator to confirm that that is the problem. If not the alternator, than your battery may be bad and not able to hold a charge. How old is your battery? More than 4 years old?
