Sounds like a bad heater control unit, or bad control module. You are bypassing the switch when you jump the relays, so usaully the switching mechanism is suspect.

AC compressor won't turn on by itself.


I would check the low pressure switch next. The switch cuts power to the compressor if the pressure is too low. The switch can fail.
Same goes for the high pressure safety switch.
As for leaving the relay bypassed, you would need to use a test light or meter to see if you are using battery power with the key off. I would not recommend it.

Someone will need to find out if the compressor clutch is failing, or if it is loosing power due to a pressure switch or other problem.
A faulty relay or switch could get hot and switch off power to the compressor.

It still seems that you don't have enough refrigerant by what you have explained .Anyway you look at it the a/c system is leaking way above what is normal for your honda.you need to get some gauges and place a small charge of refrigerant with florescent dye in it (you can buy this at your local parts store)and use a ultra violet light (This also you can buy this at your local parts store)and check to see where the leak is coming from at connections of hoses and around the compressor.This will tell you it is leaking and where and what further action needs to be taken.

The air conditioning in my 2005 T&C stopped working. Right before it stopped there was a "burnt" smell coming through the vents. What happened?

    1. The air conditioner evaporator drain hose is blocked or partially restricted, allowing condensation to build up around the evaporator and drainage tray. Clear the drain hose where it exits the passenger compartment.
    2. Check compressor clutch wiring, electrical connections and compressor clutch, and repair or replace as necessary.

My honda civic 1999 sir overheats when I turn on the air con.


If your car is getting Overheat when you turn the air conditioner On, it means that you need to repair your compressor or it will need to be replaced.

It could also be that if your car has a 2nd or separate radiator fan that should come on when the car is either hot OR when the A/C is on - perhaps it is NOT coming on and thus your car overheats. If your car does have a 2nd fan, check to see if it is coming on when you turn on your air conditioner.

Also, I would check that your radiator fan is on (even if it has only one electric fan) when the car temperature is getting near the HOT zone. At some point, the fan should come on to help circulate the air through the radiator vents and help cool the coolant (water) in the radiator.

In short, make sure your fan(s) are working okay. If not, that could be causing your car to overheat too.

Tell us news (remember rated this).

No air coming out of the vents


It sounds like the heater motor may not be operating. When you switch the heater fan on can you hear the motor running? If not then it may have blown the heater fan fuse, check the fuse's and then try it again. If the fuse is ok then it could be a faulty switch or fan motor.

Why are you running the a/c with no freon. The compressor will run even if you have no freon because it has no way of knowing there is no freon sensor in any vehicle i know of.
