Hvac (A/C & Heating) vents

[Kazeem Raheem]

Hello everyone, I have problem with my front dash vents on my 2003 Isuzu Rodeo S V6. A/C and Heat are working. They only blow out from the windshield vent and the side vent. But nothing is coming out from all the front vents. You can feel them very little but not blowing out as they should. Please what is actually going wrong here. Could it be blend door or its actuator? How do I fix this problem. Thanks for your contributions in advance.

I think you are on the right path. You will need to make sure the blend door actuator is actually working first. If you verify the actuator is operating correctly, then you have a blend door issue. In my experience most times the actuator is the culprit. I have no experience with Isuzu so you should try to find a diagram of your HVAC system on the web. I was able to find this for my chevy pickup and it lead me straight to the blend door actuator.

Good luck

I agree it does sound like the actuator on the blend door.

It might also be worth double checking the fuses before tearing apart the dash.
