2003 Ford Taurus Q&A
2003 Ford Taurus Question: Most likely problem when A/C stops working?
I have regularly maintained my 03 Ford Taurus SES and never had any major problems. Basically all of a sudden my air conditioning stopped producing cold air (but it still blows air). I don't hear any strange noises or anything else out of the ordinary. I get regular oil changes where all fluids are topped off and generally I take pretty good care of the car. I am really worried because I know A/C repairs can be the most expensive repairs a car can have! Can somebody tell me how can I find out what particular problem I might be dealing with? Also I would be grateful for any advice that might save me money if it is a costly repair! Thank you so much! Jeff - amadhatter53
Your right about air conditioning rep[airs often being costly to repair. If the blower motor blows air the controls are receiving power and working the fan blower. You don't hear any horrible noises so most likely that is really good news as well. When you operate the a/c switch do you hear a clicking sound in the engine compartment each time you turn on the a/c switch. This loud click would be the air conditioning compressor clutch engaging, The system most likely has lost its charge. If the system looses it charge and drops below a certain pressure the a/c system does not allow the compressor to turn on or it would self destruct as the refrigerant has lubricant in it to lubricate the compressor. The refrigerant is under high pressure and over time some of this pressure gets lost through the hoses and joints in the system. Leaks are often hard to find. They can be behind the dashboard in the heater and evaporator casing or in front of the radiator (the condenser often gets damaged by road debris) or the air conditioning compressor and lines in the engine compartment. It is cheapest to have the system properly diagnosed now and not wait. If you wait moisture enters the system and more damage occurs. To test, gauges are put in the system to check pressures, the system may need to be evacuated to repair leaks and refilled with the proper amount of refrigerant and lubricant. - patrick mannion
I'm sorry, Pat is correct. The most likely problem is a compressor or evap leaking. Neither one is inexspensive. Thank God you live in MD. A/C is a luxury not a nesscessity. In SW Florida you have no choice, you have to fix it. We need a/c almost 365 days a year. - backyard tech
throw a grenade(small refill of r134) in the system and if the leak happens again have the leak looked for at your auto shop before projecting disaster my a/c leak was a fill valve core $12.00 - bill m.

Any ideals if all works except cold air and gauge shows full of Freon? Thanks for any help in advance! Jerry - JPOE
