I started to explore this subject last year but before I figured out what was wrong summer was here and the top was down and I didn't given it anymore thought...however now winter is again on the doorstep and with a preganent wife I don't want to hear about "NO HEAT"!

So here's the deal...I've searched the threads and can't find anything to assist in correcting this issue. When the heat is on it will blow "normally" for a period of time and then the fans run full speed but it's like the air is blocked off suddenly and heat sort of 'seeps' out of the vents. Stopping the car, shutting down the system and restarting doesn't seem to help. The ONLY thing that really seems to help is put down the windows and allow the enterior to 'cool off' and like I said that just isn't going to work!

Any suggestions, ideas, help???????
