Could you translate your texting language to language an old person can understand.

I'm thinking that maybe you have an issue with your AC fill...r134a...maybe.

YOu have AC on and it doesn't work at idle but does at speed.

You're in an overheating thread, though...I think you should look into 'no AC' threads...different than 'no cooling' threads.

I would get AC professionally tested...also check on your hvac fan speed...the fsr gets wonky and you might be getting cool at speed because the air from 'speed' will push cold air in, even if your blower motor isn't working.

Am I close? Again, just guessing coz I don't speak your language.

What I meant was, my a/c on and the car doesn't overheat and when I stop in a light it stops blowing cold air vs when I'm driving I get cooling in the cabin. That said I'm suspecting the aux fan. My a/c will always work except that it will make car overheat prior to changing the fan 1 year ago. Now with the overheating issue that had just occurred last week I have I'm trying to see if this is related to the a/c not blowing cold air and fan is shot or not. Do you understand my language now?

I am a hipster and knew exactly what you said.

Aux fan. Enough said.

Thanks for all who helped out to sort out my problem and it happened to be the aux fan, coolant added and bled the system and installed a new Bosch fan, viola no more over heating.
