A/c blowing but not cold

have you tryed changing the thermostat it regulates the heat water flow

if they warrentied their work, that would be my first move. you can get an a/c freon recharge kit that has a guage from most auto parts stores.

Take it to a different dealer since they are rip offs it looks to me. The dye will pin point leaks very easily

cold air on passenger side of car and warm on drivers, why

It would most likely need a new evaporator or condenser. Mike. Rate 100% please.

no dealer has a reset for the a/c system by you mentioning that you replace everything it means the a/c compressor,air dryer,and the most important the orfice tube. if you hadnt replace the orfice tube wich converts the liquid into gas when it gets hot thats your problem.alot of mechanics wont change it as an a/c mechanic will.

As long as the belt is turning the compressor than the only other thing would be that the refrigerant (R-134) is not full. You can buy re-charging kits at any local auto parts store, although they recommend that you have a licensed dealer remove the old refrigerant so it dosn't go into the atmosphere. Good luck.

I had the same problem with the heater only working when accellerating. Found the overflow tank pick up tube was kinked. This of course made my coolant level low. So when the cars hot the coolant would push into the overflow, but when the car cooled the kink would prevent it from flowing back to the radiator.

the heator core has gone out this is a divise that uses hot coolent from the engine to heat the air that blowes tru your vents it is located behind the glove box some times it's tricky to reach look under the hood to find 2 hoses running side by side in to the fire wall on the passenger side to pin point the location

Not sure about the ac/radio issue, although others have posted solutions for models later than yours. The oil leaking issue is more than likely a broken or cracked gasket where the pistons of the engine are located. May want to take it to a certified mechanic to get them replaced. Not a very expensive job on a 4-cylinder car. May also want to check the draining bolt where the oil is changed and the oil filter.
