    Is a leak in the evaporator a sudden issue? I have never had that problem before. Even last year when i got the freon charged, no issues. No issues over the last year, air just slowly got less cold till I took it in to have it charged today. Then suddenly, freon coming out the vents and the compressor is not kicking on and the air is hot.

Sounds like you have a leak in the evaporator.

    The reason you likely had to charge it every year was because of a small leak in the evaporator. Now you have a big leak in the evaporator. If you dye the system it should leave traces of the dye out of the evaporator drain and on the vents.

They may not have vaccumed the line out to a negative pressure first and the system needs to have the right amount of oil in it. That migh be the problem

Car heater blowing cold air and rubber burnning


If your heater is spraying a light mist through your vents it could be your heater coil. Mine did the same thing, smell rubber burning, then started a light mist through the vents. If you don't get that checked out, it could mess up your water pump and possibly your engine

Ac is blowing hot air from vents


This job requires special tools and special training. If you lack either, you risk SERIOUS personal injury. Injury comes VERY EASILY!

You need to address oil levels, proper and legal refrigerant recovery, system evacuation, and recharge.

You were planning to also replace the receiver/dryer, correct? It also needs the oil in it measured and incorporated into the amount of oil (in %) that would need to be added. FAILURE to address these and other issues will guarantee premature system failure and likely compressor damage.

Take this job to a qualified shop.

1998 Town Car A/C Blows Hot Air But Is Charged Up


Hi - There may be 2 separate problems. On my 1991 Lincoln Town Car, there is a Thermal Blower Lockout sensor that disables the heater from blowing until the engine temperature reaches a specific temperature. This way if you have vent or floor settings and 90 degrees set and it is winter, you won't get blasted with cold air. When the vehicle warms up, the TBL circuit enables the climate control to blow the hot air. If you use the flr/def instead of the floor or vent control, the TBL should not prevent the heater from working even with a cold engine. On my car, the TBL went bad and always prevented hot air from blowing on the floor and vent settings, even when the engine was hot. Another thing to check is a thermal limitor resistor. It is designed to cut off the blower at very hot temperatures, except if the blower fan is in the hi setting.

As far as the A/C is concerned, can you verify if the clutch is engaging or not? A rapid cycling of the clutch is an indication of low freon. If you are absolutely sure that you are fully charged on freon, I think there are 2 possible causes: (1) Bad pressure switch on the accumulator is indicating low freon that is telling the compressor not to work; (2) a blocked orifice tube.

Air only blows out the bottom


if the compressor won't engage, the system can't be properly charged, because you can't see what the system pressures are. who ever charged it doesn't know what they are doing, so take it to a shop that can check pressures.
