Anyone have any idea what may be happening here? '97 328i will run normally while a/c is turned off, however when a/c is turned on the car will begin to overheat. I recently replaced the water pump, thermostat, and radiator because of this, but it did not solve the problem. Plus I had to replace the radiator because the radiator neck busted. And, like I said the car runs normal until the a/c is turned on.
Any help would be appreciated?
