When I turn the AC or heater on the fan does not come on. Nothing coming out of the vents. I checked both fuses under the dash and they appear to be in good condition. Any suggestions?? Thank you for your input.

sounds like compressor isn't working properly or heater vacuum is opening vent to heater core.try turning on ac and if it cuts on and off repeatedly every few seconds the freon level is not correct or high pressure switch may not be working make sure radiator fan comes on when ac is on.if all this is working properly check vacuum hoses to heater may be opening vent doors to heater.hope this helps
It sounds like the heater motor may not be operating. When you switch the heater fan on can you hear the motor running? If not then it may have blown the heater fan fuse, check the fuse's and then try it again. If the fuse is ok then it could be a faulty switch or fan motor.
With the engine off, radio too, turn the key on and try the heater fan on all speeds. No fan, check the fuses. Fan is ok, check the coolant level, if thats fine, then check for a mouse nest in the duct work. Frankster016
