When I turn on my heater sometimes it comes on right away and other times the blower takes about 5 minutes to come on. Help.

With intermittent issues, can be hard to tell. When the problem occurs, check the ac heater fuse for voltage, use voltage tester, you have to test with the key on. Also there is a fusible link in the diagram, you can check.

At the blower motor, purple wire is voltage with key and hvac turned on. Black is ground. I can't tell exacly where the problem is located, without testing.
