Q: The wiper motor on my dodge aries seems to be malfunctioning. The wipers stop in mid stroke, and require a pull to get them going again. I was advised to either replace the brushes, or replace the motor. If I were to replace the brushes where are they and is there some where onthe web where I can get a diagram or instructions on how to do this. Secondly to remove the wiper motor, one of the bolts is at the bottom and very difficult to remove. What kind of a wrench do I need to get, does it need to be a specialized type of wrench. Please advise.
A: Some people have cleaned all visible old grease off and replaced with a good, clean silicone grease.
It freed them enough to restore good operation.
If you take it off, check All-Parts for a new unit.
Q: The fuel injection runs extremely rich at all times, fouling the plugs in a matter of seconds if idling.
The code says the oxygen sensor is stuck at rich, it has been replaced with no improvement.
Could the fuel pressure regulator on the throttle body be the problem?
A: Yes, it can....
.... and if it was - and the fuel was being poured into the engine - then the o2 sensor would be stuck at rich....
Q: Engine overheats; Replaced radiator, hoses, thermostat and the Timing belt was also replaced recently. Temperature goes up all the way.
A: If this car has an electric fan, it might not be coming on. Check that it comes on at least 15 minutes after you first start it. The temperature gauge might be bad.Does it go all the way to red hot immediately when you start it? If so then the temperature gauge is bad.Did you change the thermostat yourself? If so,make sure you didn't put it in backwards. If it is working properly you should be able to start the car without the radiator cap on and wait about 10 or 15 minutes. You should be able to see the coolant flowing and it should be hot to the touch. If the water doesn't get hot then your thermostat is not working right.
The only other thing that may be going on is that your ignition timing is way too advaced or you may have a blockage in the coolant system somewhere like a rust ball or something.
