Engine Cooling problem
1991 Pontiac 6000 6 cyl Front Wheel Drive Automatic

I changed the cylinoid and the temperature sensor under the thermostat. The fan will not engage at proper temerature or when A/C is swithced to on position. The fan can be jumpered to function with jumper test lead. This began after a Premium Car wash where the under carriage was washed.
