    So seen threads about this but mine doesn't seem to be low on freon. Now all vents warm . Ac compressor is running doesn't cycle like low on freon. Line coming from compressor hot but coming out of condenser not even warm . Thinking compressor failing clogging filter in condenser line ? thoughts ?

    The pressure line should be pretty warm to hot. The larger line should NOT be warm, it should be cold to the touch. If it is sweating / cold to the touch, it seems that things are working correctly regarding the A/C side. The blend-air door can be broken, causing more warm than cold air to be discharged. The evap core could be clogged with trash so that air can't pass through it to dump the heat.

    As always, gauges are your friend. If the pressures are correct, the compressor is fine. No way to determine that except to hook up gauges on high and low side.

    Yea no access to gauges so doing caveman style diagnosing lol. Forgot to mention low side coming from evaporator not even cold or sweathing. High side coming out of condenser not even warm. Got extended warranty so will be taking it in in a couple weeks .Had to wait a month for appointment.
    Blend door seems to be working can here movement and temp switches . Plus driver side vent was cold couple weeks ago. Will see what dealer finds . Thanks for reply

    Are you CERTAIN the compressor is running? Describe what you are, or are not, seeing.
