Hello, my problems include ABS lights, brake lights, check charging system. The AC panel will come on and then shut off when you accelerate. The gas driver side door will not work, rolling window up or down while battery light is showing and check charging system are showing. Check charging system will set off and batter light will shut off and then my AC will work and the door will work. Please help. New battery.

It sounds like there may be a problem with the alternator. Follow this simple test to see if it is charging. We need to first determine if the alternator is bad or there is a different problem.

Thank you I recently purchased a multimeter and will run the tests you suggested I'm hoping it is the alternator and not a major electrical issue. I will keep you posted on the outcome or if I have problems with the test thanks again!

I'll keep my fingers crossed for you. Let me know. Also, keep in mind, you should also check the main ground from the battery to the engine block as well as the body ground. If you need direction, let me know.
