Hi Linda, there may be various factors involved with the electrical related issues, I highly recommend for you to have the vehicle go through diagnostics to determine the exact cause, because depending on guess work will cost more in the long run. You can also call part sales stores and ask them to see if they can plug in their scanners to read the faults in your car.


check the large fuses in box also if it has them, maybe shaking the wiring at box will jar a connection
