Craziest thing

Postby sinapu [OP] » August 4th 2019, 8:08pm

So I have a 2005 Safari AWD. The AC works great but all of a sudden it starts blowing out warm air.. and here is where the wierd part is.. if I over accelerate it fixes the problem every time!! Feels like something was sticking and I temporarily fixed it.
I happens 90% of the time when I'm stopped incase it makes a difference.
Has anyone experienced this?

would that explain random changing from cold to hot and the ability to correct it by revving the engine?
