Mike, I talked to Webasto tech support and discussed the problem I am having. The unit didn't fire when I turned it on. Cold air was coming out of the exhaust. Pump ran and the fans came on. Webasto said that the problem may be the nozzle, fuel filter and some of the sensors. I have a nozzle and fuel filter from previous problems so I am going to try the suggestions from Webasto and go from there. We are considering going north to TN to see one of my wife's doctors and I must have the Webasto working before I go. I'll keep the forum in mind if I get stuck.
