I am able to turn on the heat, but it goes cold quickly. So I turn the dial to cold and back to heat then it warms up again briefly then goes cold again. Then later in the day I turned on the heat and it stayed on with no issues. Is it the contacts on the switch or something else?

Here are a few things you can check on your own.
- Check the blower motor operations.
- Listen to your motor and see if it changes speeds when you turn the knob.
- If the motor changes speeds then the motor and associated resisters are working fine.
- You could have a problem with recirculation door. This could be broken or blocking the air from coming in.
- Check the recirculation door by removing the blower and looking at the door. Use a mirror to physically look at the door.
- If this is your problem, then you will need to replace the part in your truck.

You might have a problem with the thermostat or one of the switches.
