[QUOTE="hmwave, post: 16549290, member: 10968"] Searched the forum for information but couldn't find much. Wondered if anyone has ideas on this problem, or if it's a known issue with a specific fix. 2003 Cobra has sat inside in dry garage for 4-5yrs, very seldom driven. Took her out in Summer and noticed the A/C wouldn't blow cold. I put it down to possibly low refrigerant given the car has sat for so long. But, drove her yesterday in 40-50F temps and there's no heat at all from the vents. Tried rotating the controls multiple times, switching off and on, but nothing, no heat at all. The fan is running and air is flowing proportional to the fan speed, and the air flow can be properly directed to feet, face, or windshield defrost with the control. It's been a while since I spent much time working on her, but will dig in when I have time to determine the root cause, but wondered if anyone has ideas on what's wrong, what to check to resolve the problem. Possibilities: 1) Air block or fluid lock somewhere in the heat exchanger, or supply from the block? Can I bleed it somewhere to resolve? 2) Not sure if the heat flow path damper(s) are electrically actuated so possibly stuck shut, an actuator(s) has failed, or maybe a fuse blown? 3) Seems odd the A/C wouldn't blow cold in Summer, and now there's no heat in Winter. Coincidence or maybe a clue of what's wrong? Thanks for any advice. [/QUOTE]
