If your heater is not working then you either are not getting coolant to the heater, your thermostat is bad or your HVAC fan is not working or your water pump is bad.

 

Well, the AC was blowing cold today. I drove it around for 25 miles or so and there were no overheating issues. A lot of air came out when I bled the system so that may have been the problem. I also bought bosch platinum + 4's today so I'll see what results I get from that and get back to you.

 

It's running great again. The old plugs were in very bad shape. Thanks for the advice on the cooling system. I just took a trip to sedona and everything went great.

 

Glad to hear it.
