Customer: 1999 pontiac grandam 3.4l cooling fans don't come on when coolant temp is around 150 degrees, also don't come on with a c on. a c doesn't produce cold air. a c doesn't produce cold air. removed connector from coolant temp sensor and cooling fans come on. Put the pan back in place and start all of the bolts. tighten all until they are finger tight, make sure the gasket has not shifted, then start tightening with a wrench. fill the transmission with the recommended fluid (probably dexron iii or mercon) and check the level.
