I've posted a few times about my heat not working with out many replys so I was hoping to get some help this time around. My heater stopped working so I replaced the blower motor and it worked fine after that. All night it was fine and then this morning I turned on the car and there was no heat, I was pissed. I left work at 9am after being there for about an hour for an apointment and when started the car the heat came right on. It worked all day with no problems. I bet $100 that when I start that bitch in the morning when it's 30 degrees out there will be no heat. I'm starting to think that either the coldness is effecting it or there is a wiring issue. Any suggestions?

 

i wonder if it has a heater core?

 

Is it the blower that is not working or the temperature or both? Check your ***** to make sure they aren't cracked.

 

the heater core is working fine because when the blower isn't pushing any air through the vents I can still feel heat coming out just not alot because there is nothing to blow it out. The engine heats up fine as well. Someone had mentioned that it may be a bad relay so I'm going to check into that.

 

Check to see if it has power and ground at the blower connector when it is acting up.
