03 S-Type R "HELP" !!!A/C Problem!!!!! blows hot air

\015 Hi everyone OK this is my problem I got a 2003 S-Type R my front left and right and the rear back vents is blowing hot air when I turn on the A/C and the front middle vent is a lil cold but not as cold as it should be. So I took it to a shop after it got the A/C recharge it was doing the same thing so I took it to another shop that work''''s on Jags they put it on the machine and told me it was the heater valve and auxiliary water pump so I got those change and it still does the same thing.

Answers :

I had the same problem. exactly. the problem I determined was that the water flow to the heater core is not being restricted by the DCCV. ( heater valve ) My dealer tried replacing everything electronic. and then wanted me to buy a 1400.00 control head. I said no way. I determined that there was no power going to the center yellow wire on the DCCV. Therefore it will default to full hot when no electricity is present. I checked the fuse and had power but none at the connector of the DCCV. I began to follow the harness from the DCCV to the chassis of the vehicle and in the right front coner of the car under the headlight attached to a frame rail. right where everything drips if you have a leak is a connector that has the 3 wires for the DCCV. it is a 8 place connector with 7 wires in it. It had become corroded inside from a leaking DCCV and overtime deteriated the terminal. I replace the connector and all problems were fixed when I had power to the DVVC. I have pictures if you need them. [email protected]
This is going to be a problem with your air door actuators they most likelly are electronic controled, seems to be like the two places you took it to don't know what they are doing, this is simple, the doors controling heat and cold are not working propelly, have your car take to another place, specially if they specialize in a/c system, and ask to have your blend door system inspected, since the blend door is the one controling heat and cold,
