Question about 1998 Cadillac DeVille
AC COMPRESSOR WANT COME ON AND SOMETHING CLICKS UNDER THE HOOD AND ENGINE MISSES
Either the fan is not turning on, unlikely or the radiator is plugged with mud. Wash with garden hose. When ac selected and snowflake light comes on does it blink then go out or stay on? And when ac selected does cooling fan under hood come on? It should we it her or not the compressor kicks or not. But if gets hot with ac selected then compressor turns but lack of airflow to cool engine radiator and ac condensor. Now. Cataliac threw u a curve ball. It's one or two fans for cooling under food and they are sometimes two speed. If two wires to motor then single speed if three wires then dual speed. Suggest take garden hose and spray the hell out of it. And also this car is notorious for getting leaves and debris caught between radiator and condensor. Bad part is the upper radiator support is not removable. So remove plastic cover that stretches from fender to fender and remove both long winded upper radiator mount screws and lean top of radiator to words rear of car and with flashlight check to see how big the mice nest is between radiator And condenser. Clean.
