Hello, I have a 2013 Ford cmax and a few months ago I changed the AC compressor. It's been blowing fine at 43 degrees since June. Today I'm seeing an issue where if I'm sitting still it blows cold but when I accelerate it warms up to about 75 blowing out of the vents. Then when I'm driving it will alternate where it'll blow cool then warm then cool then warm. Any ideas?
