Anybody pull their heater out of the vehicle......Took it for its first drive yesterday, heavy rain, cold, no heat....... fogged up windshield and leaks.... about 15 min into the drive the water started coming under the top and dripping off the sun visors, the windshield fogged up as well as the side windows. While testing the other positions on the heater controls the fan worked great, when in the defrost position nothing, the fan is still running but nothing is coming out, as for the heat, I think the thermostat is stuck open or the previous owner removed it. I looked in my Chiltons manual and it shows a break down of the heater but nothing about its removal. Any ideas........
