I just replaced the thermostat and my car still wont blow out heat. I can feel hot air blowing out from the floor but it's very weak. What else do I need to check.
I replaced my thromostat and my car still wont blow out any heat. I can feel it comming out at the bottom floor vents but it's very weak. It was doing that before I changed the thromstat I thought that was it. I think I have heat but it's just not blowing out. How is it the blower motor or something else if so what do I check
