Having a problem with my heat or A/C to come on. Sometimes it will with no problems but some times it wont even turn on. I have replaced the resistor but that did not fix the problems. Any suggestions?

Good morning,

Do you mean the blower motor is not working?

If you do, I would verify voltage to the blower when it does not work. The resistor is a common failure but the motor itself is also very common.

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