To tell you what's wrong, we need to know what diagnostic codes are stored in the computer. To check them, be prepared with a pen and paper to write them down. Turn on the ignition, but you don't have to start the car. Hold down the OFF and WARMER buttons on the climate control system. If you have an analog dashboard, it will have to be the OFF and passenger-side WARMER button. All the dashboard lights will go on in a few seconds, then it will go through all of the codes. Write them down. They will be 6 characters long, such as RS0038 or PC0135, followed by either CURRENT or HISTORY. Write them down, then post them here and somebody will be able to tell you what to do next.
