I am having a problem with the cars heating and air conditioning system. The cars blower motor does not work on the highest setting. On the lower settings the blower works but it seems to be blowing out only cold air. So far I have flushed the cars radiator and installed a new thermostat and gasket. Please help me find the problem.

Replace the blower motor resistor, its located next to the blower motor under the dash. It should have a plug going to it and held in it heater box by either 2 7mm bolts or 2 screws.
