Have you changed the oil filter? Change the oil and filter.(USE the AC Delco filter and the 10W - 30 oil..(Wal-Mart oil is fine - it's made by a major refinery - HINT- Walmart does not own a refinery!!!) They buy the oil, have it put in their marked containers and sell it cheaper then others) I ONLY use Wal-Mart oil in everything!!..you might try a pint of Lucas oil treatment.. See if the new filter helps.. sometimes they are defective and block oil flow and the pressure makes it flow..

If the washer fluid is not pumping and they're new, something isn't connected right. They're obviously not getting power. Either that or the pumps didn't work in the first place.

Hey Laurlees, Have you had your alternator checked for voltage and amperage output?? This MIGHT be you whole problem.. ... (disconnect the "under the hood light" switch.)..

I had the same problem on a Dodge 6 cyl. It was totally frustrating until I replaced the fuel pump. You don't say what type vehicle, but if it an older model with an inline fuel filter that can cause the same symptoms. If there is a fuel filter replace it. Another good trick is to take your fuel line loose at the carburetor or throttle body and blow compressed air through the line into the tank. Some older models have a "sock" of mesh on the pickup end inside the tank and tiny bits accumulate on that and can plug off the flow. Take the gas cap off before you blow air into the tank. I hope this works. If not you may be changing the fuel pump. UGH

Unscrew the old one and swap in the new one.

You can copy the key, but without a matching programmed anti-theft key fob, it won't work.

The park switch is built into the motor. YOu need a new motor. Find an independent shop and have them replace with a rebuilt or new aftermarket unit instead of a dealer unit. The labor guide shows 1.4 hours to replace the motor

Hi Jason. Sounds like you are on the right track with the flow of hot coolant not stopping. Check your heater control valve to make sure it is stopping the flow of coolant through the rear heater core. Let me know. Hope this helps.

The headlight bulb is defective.

Test your positive and negative cables for continuity. Sounds like you have a cable not doing the job. Also be sure to check connection is secure

Without testing that would be hard to say ! Have checked for DTC'S - diagnostic trouble codes . In all the modules , not just the PCM , obd .

This sounds like a CV joint is bad. It is binding up and locking and then slips when you move.
