Most likely cause is low or no refrigerant. Question is wears a leaking from? There are refrigerants with ultraviolet Diane them that will blow when you put a black light on it to show where it is leaking from such as host connections or seals and the compressor itself, but you would not be able to see leaks in your parts that are under the dash. The cheap refrigerants that act as sealants don't do much, the $25.00 stuff may work. A can of refrigerant with a hose around $15.00. If you are a hottie the parts store guys will probably put it in for you it only takes a minute. Otherwise send the wife! mine is gorgeous I haven't had to put a battery in or wipers on in years!

    Diane? I meant , dye in them. Voice recognition messed up, I don't type much. Blow? Glow. The compressor will not engage if refrigerant is low. Some fill kits come with a guage. I have to stop answering stuff at 3a.m. I really botched this one. Glad you got the gist.

My 99 dodge intrepid heater control stays blowing and wont light up and wont stop blowing unless i pull the fuse and nonew of the controls work

Are the different speeds working on the blower or is this stuck on just one speed ??? It seem as if the relay for the blower is fused together in the on position an can no longer be controlled by the switch. If this blower is not a relay controlled unit then most likely the blower switch is no longer working.

Heater/ A/c blower wont work circuit breaker wont reset

If the circuit breaker trips as soon as you reset it, then you have a dead short somewhere. It can be in the wiring or the blower motor may be bad. Another possibility is a shorted blower motor speed control or blower motor resistor pack.

Blower motor wont work

Disconnect connector at blower under pass side of dash.Check for power & ground with the blower switch in the #4 speed (High).Most Likely a blower motor if all 4 speeds are out.If high works but no other speeds,you need a blower resistor.Blower easy to change 3 screws & one connector.hope this helps
