My air conditioning is blowing cold air but it directs the flow to the windshield and floor and not from the vents in the dash. It works this way in both the manual and automatic modes. I have checked the fuses under the dash (passenger side, far right, next to kick panel) and they are okay. It started doing this about three weeks ago and I could get it to work by pressing the auto button and then the off button, wait a couple seconds and press the auto button and the system would start blowing air out at the floor and then shift to the dash vents and work fine.
Every time you would shut the car off you would have to go through this sequence to get it to blow air out the vents. Now this no longer works. I am fairly handy and do not mind getting dirty, what should I look for and where. (Looks like a jungle under the dash and hood)! Note: Air flow indicator on dash indicates that the air should be coming out of the dash vents but it is coming out at the windshield and floor.
I checked the A/C and heater control per your suggestion. All functions of the control work as per the system response check, but the major air flow is at the windshield (defroster) regardless of the mode (auto, manual, floor, mid, recirculating, front, heat or cooling) that the controls indicate. There is a trace of air coming out of the heat ducts also but not the normal air flow, one could say that it is minimal.
I believe the control which switches the system to the different areas, windshield/floor/mid vents is not working, if so where is it, what has to be removed to get to it? Is there relay and if so where is it. I am assuming the control is electrical and not vacuum.
Had the computer scanned and no codes were present.
Thanks for your help.
have the same problem?
