I just had my QJet rebuilt. In the process of removing it I discovered that the Electronic connector on the right front corner was burned and no longer any good. The part it goes on is called a solenoid-dual capacity pump in the GM parts breakdown. I spent the better part of three weeks trying to find a correct replacement part. The part is no longer available from GM. But I have found a source for the repair part plus many others that are hard to find. The company is Pacific Industrial Components Inc. Eugene OR 97402 800-547-5328. The part number is a 5615C

I spoke with the company and they deal through small jobbers across the U.S.. If you cannot find someone locally that handles their products call them they'll hook you up.
