I have a 2003 Mazda Protege with ~98,000 miles. I took a road trip from Louisiana up to Idaho this summer. On the outset of the road trip I recharged my AC myself, but over charged it by turning the can up-side-down. To solve this problem I bled off enough R-134a until the AC clutch would kick-on and stay on. The AC worked fine until somewhere in Missouri where it just went out. Eventually, my car overheated outside Denver, CO in the mountains. I took it to the shop and had the radiator and thermostat replaced, which coincidentally fixed my AC problem. From Colorado up to Idaho my AC and coolant systems worked fine, but coming down through Southern Utah and Arizona, I discovered my car would overheat whenever I had the AC on and was going up a hill (i.E. >4000 rpms and under 40 mph).
It would not overheat if the AC were off and I had high rpms with low traveling speed.
Any help would be great!
have the same problem?
