well, I just finished driving home from work (2 hour drive) without any heat... I've determined that my luck has run out... (earlier this week a rock hit my windshield right on the driverside... Ferrari said it would only cost 4300.00 to replace it... no problem, I can't think of any thing else I'd love to spend that kinda money on, can you?) well, back to the heat thing, I removed all the trim panels under the hood and now have the heater valve and other mysterious gadgets exposed. can anyone tell me which part is most likely bad? the stealership.... OOPS, I mean dealership has no idea which part most likely failed. They think it could be the contol unit (1800.00), or maybe the hot water valve (650.00), or maybe even a small cpu somewhere. can anyone tell me if they have been down this road before? I just read the post about the 102K mile car... that great... I've only got 29K and hope this is the last of my problems....I guess the windshield has me a little bitter!!!
