To perform a "backyard" check for a charge, assuming that you do not have A/C gauges: Open the hood. Look for aluminum tubes going thru the firewall. Somewhere, on each tube, there will be a grey cap. One has an "H" on it, the other, an "L". Remove the "L" cap, and, using a suitable pointy tool, depress the center of the little valve thing (it is just like a bicycle tire valve). Do NOT put your face over it. Depress the center of the valve for less than 1 second. If anything like gas pressure shoots out, you have some charge in the system. Nothing comes out, you have a leak somewhere.

Make sure your fan clutch is working. No fan, no cooling of the condenser, no heat dissipation, no cold air. Start the truck and make sure you feel air movement, a lot.

We have a/c in the front but we have no cold air in the back...the fan blows but not cool air..ive changed to rear a/c filter so i know thats not the problem


You will need to replace the Blend Door Actuator. This part controls the flow of air to the vents and when it fails, you will not get air flow to the back. Also make sure your freon is fully charged up

If it blows, but not cold, Either you have a leak in the system, the condenser fan isn't running (although it would cool on the highway forcing air through the condenser.. It needs a partial charge with UV dye so any leaks can be traced...

Ac on 01 eclipse


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.
