Kovert

Need some help. I have a 2012 TL with 144000 miles. I had the entire a/c system replaced last year (compressor, condenser, drier, evaporator, etc.)...now it's only blowing cold intermittently. I changed the clutch relay and had it checked for freon leaks...pepboys said it was full with perfect pressures. I'm not sure what the problem is...sometimes the compressor is engaged and sometimes it's not. What could be the problem?

You mentioned you replaced the relay in the engine compartment. I would check this as its a relatively cheap part under 15$. This was the issue on our TL after we spent money to recharge the ac system unnecessarily. I would swap out the relay with another new one and see if it solves the issue since its such a cheap part.

There was another thread with the OP having issues with the blend door for temperature controls. Check this thread:
