A/C issue; let it 'warm-up'???
its a 95 mercury tracer, 1.8L dohc, about 126k miles. a/c works, but it has to 'warm-up' or something first, especially on hot days...and it doesnt get as cold as it should i think. it feels like it maybe hits 60 degrees? nowhere near correct. anyway, i got out my recharge kit (yes, it is r-134a, from the factory) to test the pressure first, and on the money, 45 psi. any ideas what it may be? i know really nothing about A/C systems, so if anyone can tell me so i dont have to spend a fortune on some mechanic to tell me that i have a bad accumulator, or orifice tube, or evaporator..id like to know if this is something fairly easily recognizable in common cooling problems. thanks!
