Hi Everyone,

New to the forum and also new to Auto AC repairs.

Recently acquired the tools (major ones) and did a few repairs already. I am not new to Automotive repairs though, as an enthusiast i do everything including Mechanical, electrical, audio and body.

I just needed some opinions on this one.

The AC works when the place is cool, but during the day it doesn't cool well. The low side line from the evaporator is cold and a lot of condensation on the line.
The only time the compressor cycles is when driving, but this also happens infrequently.

How should i approach this?

I would check for blocked airflow in the evaporator (leaves, mouse nest, etc) and reheating from the heater core (water valve not turning off when dash control is on full cold). Low side line getting cold and compressor cycling indicates that the refrigeration system is working fairly well.

Thanks for your reply mk

The heater was disconnected some time now. Will check the evaporator once i decide to take it down.

Question, there is more than normal amount of water coming out of the evaporator drain hose, could this mean the evaporator is icing up?

Thanks.

Lots of water coming out is normal in a humid climate.

If there is an ice up the water will stop coming out until after you park and turn the system off, then a considerable amount of water will eventually come out as the ice melts.

The number one cause of mobile a/c discomfort is loss of refrigerant--I'd play the odds- discharge/reclaim and recharge to factory spec.

-------------------------
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
