The digital climate control heater lights up fine, but nothing seems to come out the vents and no sound at all, the defrost and heater doesn't work, no heat. I replaced thermostat last month. All fluids are fine, I use 50/50 anti antifreeze, What are estimates if I need parts or if I can easy fix myself how to fix it myself? Please get back to me soon, please include a video so I can watch. Thanks Alicia

Please show me what steps to check before all repairs thanks.

Please give me a check list what to look for and which fuses to check and where they are located at, under the hood, passenger side door panel etc. Please send a link to watch video step by step instructions so I may know how and what to look for. If need to buy something a price list would be helpful for my low budget. Thanks, Alicia

Good morning,

From your description, it sounds like your blower motor is not working.

I will attach a wiring diagram for you to view. You will need a voltmeter or test light to do some checks.

Thanks Roy, I just got done fixing the problem, the only differences was with the new heater motor blower is there's two different holes to attach the rubber hose that connects to the motor blower and then hook it back behind the blower that the diagram didn't show in your message, but I figured that part on my own. LOL

But it does kind of work, it just doesn't hard enough through the vents after I installed it. I made sure all vents are opened and they are. But the defroster works but not coming through the front vents as hard as they should come out like they do for defroster? If you have a suggestion, I'm open to hearing what you have to say. Thanks Roy. Alicia

How does the air blow on the floor?

Do all the blower speeds work correctly?
