It could be your low pressure cycle switch is going bad. Check the connection to the switch and it's is located on the A/C Accumulator. The other thing to check is the A/C relay and that is located in the glove box. There is a panel in the glove box that say's relay, there is three relays in there and one of the out side relay's out of the three is the A/C. can not remember which one it is. The middle relay is the fuel pump and the other one is the third break light. Switch the two out side relays and see if your A/C get's better. the other thing too is if the R134a is just a little low, and needs to be topped off. Good luck and hope this helps. if your going to try to recharge the A/C system your self, keep in mind not to over charge.

you may not have enough refrigerant. a low charge can cause the rear in this dual system to not work for beans. charge with a can of uv and find the leak. fix the leak. evac the system and recharge. i think you take 4 lbs, but check the accumulator sticker. you may want to just change the accum at the same time.

That "thing" is part of the compressor clutch. When it’s spinning the clutch is engaged, when it stops the compressor is off. If it’s constantly cycling, you probably don’t have enough freon in the system. But remember, however the gas escaped before, it will escape again, unless you fix the leak.

the problem is probably the heater core, it can become clogged with dribris. this stops heat from the engine getting to it and then no heat.

If you are absolutely confident the AC compressor is not kicking out on low pressure then it is the blend door actuator.
The blend door determines how much air blows through the heater core or evaporator.
The actuator can be purchased at dealer and maybe at a local part store.
