The dash computer has been changed due to other problems now fixed, but this did not correct the AC problem. I would like to add more information, but this is all there is to what i know. Any questions? Any suggestions? Thanks for any help, Donn Hammer Time Ultimate Carjunky / Moderator Jul 12, 2010, 10:55 AM Post #2 of 4 (1655 views) Re: demon possessed AC Sign In Please be a little more clear on the problem. Is the temp going warm on acceleration? Is the blower changing directions? What's it doing. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

The temp going cold on acceleration The blower is changing directions. The AC can be used normally at any time. I should have stated that whether the AC is on or not, it will blow cold air forcefully out of the center vents (body shot) when accelerating. It does not matter how the heater is set or if the blower is set to another location. The car just decides its going to blow the cold air. An example? - I am driving on the freeway with the temperature control set at 70 degrees and direction controls are set to go to the floor. I come to a hill or speed up and then then air conditioner (which is NOT turned on), starts blowing cold until I stop accelerating. It then returns to normal. I hope this clears the question. - thanks - Donn Hammer Time Ultimate Carjunky / Moderator Jul 12, 2010, 11:41 AM Post #4 of 4 (1648 views) Re: demon possessed AC Sign In With so many different control issues there I would tend to believe the Control head is bad but that will require a professional scan tool to be able to confirm that. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
