Have you checked the codes in your engine bay. The codes can be read through a diagnostic unit next to the washer reservoir. There are two little black boxes with covers. Pull the cover off the left one and plug in the test wire that is attached to the cover. Plug the test wire into the number 2 hole to read Fuel, or the number 6 hole to read ignition. Once plugged in, turn key to on position. Push the button and a red light will come on. Hold for 1 second and watch the light. the codes are the number of times the light flashes. For example, the light may flash once, then stop, then flash twice, then stop, then three times. That would be a 1-2-3 code. continue to press the button until code start duplicating themselves. Post the codes on this site and someone will help you diagnos your problem.
