On my heater speed switch it wont blow out air on the highest setting. There are 4 choices and since the highest speed quit working the other speeds are not blowing as hard as they used to be. What can I do to fix this without a costly mechanic bill, which I cant afford?

Check for voltage at the blower motor electrical connection with the speed on full, if there is no voltage with the fan on high, then replace the switch. If there is voltage then try a new blower motor.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
