here is the current situation.... took off the top, power unit etc so I had a clean shot at the parking station and the drain tubes from the purge unit. I toka syringe, filled it with a windex/ammonia water solution and pushed the solution through the small holes under the parking sponges. Solution came through each tube s the solution was squirted in the holes. Conclusion? purge unit is open, Whether it is working has yet to be determined. I will cycle a couple deep cleanings and see if something comes out the tubes. Any other suggestions? Taking off the top is a pain as the screws to put it back on is a real test. Been this far, hate to quit now!!!
