I have no air coming out of the vents. My ac condensor spins but it reads an ac relay. I changed the blower motor and the blower motor resistor. My fuses seem to all be good too when tested. If I strait wire my blower motor it comes on but it won’t come on when it isn’t. My switches are all fine and come on but no air and my parts inside the dash get hot. I changed my thermostat also.

I have no heat or air whatsoever coming out of my vents. I changed the actuators inside the dash as well and still nothing comes out. There’s also a loud buzzing noise from my fuse box inside my car that buzzes for a long period of time.

Reading your post and it makes me think that the buzzing hearing is from a relay in your fuse box. Relays may have burnt out. That could also control your air. Do you get air in the car if you put it just on vent switch from interior air. Let me know how you make out

No, I don’t get any air whatsoever through my vents. I checked my relays, and they all seem to be okay with a light tester, but Idk what else it could be. Idk much about vehicles but I’ve had my car since it was brand new right off the lot with 5 miles so it’s kind of special to me. Im thinking might be a short somewhere but idk where to start.

Hi,

I noticed it has been a couple of days since you've been contacted. Have you been able to make any progress?

If you haven't, let me know as much as you can as far as what has been done and checked and your findings to date.

Take care,

Joe
