    My 1998 Mercury Villager is not blowing as cold as it should in the front and blowing very cold air in the rear of the vehicle, i have tried to recharge the a/c, but when i connected the canister to check the A/C it read that the A/C was full and didnt need a recharge. What could cause it to be cold in the rear of the vehicle but not in the front? is there 2 seperate recharge ppoints?

Check the cooling system, particularly the radiator to make sure it is not partially plugged. Additionally, check the radiator fan for proper operation. If the engine temperature is running way above normal, some of the heat is transferred to the air-conditioning condenser, which causes the air-conditioner to lose efficiency. As for your question about a "limiter" switch, there is a high-pressure switch in the air-conditioning system that cuts the compressor out when the pressure gets too high.

Air only comes out thru defrost but when you let let go of the accelator it starts to come out thru the vents 2003 mercury grand marquis


It sounds like a vacumn problem. When the heater controls loose vacumn it defaults to the defrost position. When your car decels your engine vacumn is at its highest. Check your vacumn lines for damage. Check the control panel for a vacumn leak. If you take out the controls and hear a suction noise than the control switch is leaking.

1997 ford e250 van. heat only no cool air. New heat valve (vac. controld). If dash control knob is on red or blue (hot or cold) hot air comes out of floor, mix, or defrost depending on position of delivery...


One of your deflector door servos or the door itself, is hanging up. To determine this more clearly, run your vehicle for about two minutes and shut down the engine. Move your function selector knob from defrost to floor to panel and listen carefully for a sweeeping sound. if you do not hear this sound you've got to check under the dash for a loose vacuum line or under the hood for a loose or broken line to the vacuum accumulator. The vacuum accumulator is a large black ball on the firewall with only two lines connected to it. One line is about3/32nds of an inch and the other will be about one quarter inch. Check these lines well, for they control ALL the functions within yout climate control. Best of luck my friend, Dana

Depending on the year of the car, you may have to get the system recharged. It is actually common to do this in cars that are more than a few years old.
