A/C slow to cool
I am new to the forum so bear with me.
I have a 95 E420 and live in Phoenix Arizona, outside temps are 100+now but we use the A/C most all year.
My problem is that the A/C takes a very long time (16+ mins) before it starts to blow cold air. I didn't have this problem last year so it is something new. Had the a/c checked and the mechanic said I needed to flush the cooling system? This didn't seem logical so I am posting my question here. Any suggestions?
