A/C problems.....

[Therittz]

Okay I bought a 2010 hyundai genesis 4.6 from a good friend of mine about a year ago and all has been great up until now!! It started with maybe 3 or 4 months ago I noticed that my cooling fan wasn't working correctly due to the plug of the fan which plugs into the module under the fuse box. What I found was that the module was messed up from a bad connection so I replaced module and fan came on! So fast forward to today and I've had to replace my cooling fan assembly because of the plug ..... the connectors have gotten bad within the plug so I ordered 1 assembly from advanced auto parts and installed along with replacing the thermostat, temperature sensor and wiring harness to temperature sensor and also even replaced the mass airflow tube (just noting everything I've replaced) ...... but now my a/c is not working....for example whenever I used to set it at 68°f, it felt like 68°f but now at 68°f it feels like normal air coming out of vents. I popped the hood and felt the a/c line and it was cold so there's freon in it and it's compressing it because it's cold(line) but it's not transferring that cold farther than that a/c line! Any help would be greatly appreciated!

Does you AC cool correctly while you are driving at 40 MPH and above?

Sorry for the delay.....no it doesn't. It's really weird because the a/c line under the hood is cold as if it's compressing the freon but it's not allowing it to come into the car if that makes sense??

For the year that your car is, certainly it is Suva (R-134a) and not Freon (R-12).
Possibly, your air temperature blend door has stuck in a semi-heat position.

Are you talking about the door type flap underneath the filter....inside the filter box???

Well I was referring to the refrigerant in the car....

I do understand that, and I know that sort of thing bothers me more than it should...

I don't think so, that one is probably to select fresh or recycled air. The blend door selects how much air goes through the heater core after going through the evaporator. It is likely closer to the center under the dash. I don't have the details on your year car. Of course, this is just a guess, and it may not be a very good one from this distance.
