Hi, I was hoping someone can help me out. I had a leak from the cowl which leaked into the cabin shorting out many of the HVAC components. I replaced the blower resistor motor, and the ac actuator door switch. Now that I did that, the vents are blowing pretty weakly. I have heat and A/C, and the climate control works fine on both sides. Its just that im not getting much air flow coming out of the vents. Is it the blower motor going bad, or another underlying problem?

 

If you have heat, and ac my best guess would be the blower motor unless while you had things apart, you somehow dislodged the vent air pathway (don't know the technical term but the hosing that the air runs through to come out of the vents) if this was party dislodged it would also explain the reduction in air flow

 

Maybe a wet cabin air filter?

 

Thanks for the advice. I checked the cabin air filter, and its fine. Bone dry. Now, the airflow is fine, but im not getting heat from both sides of the car. One side is blowing hot, the other cold. Strange, because the A/C actuator door was just changed. Maybe it wasn't installed properly? Fuse? I'm stumped

 

There is a re-learn procedure for some actuators after replacing them. If I'm not mistaken, It is simply turn off the HVAC system and turn the key to the run position and wait a few minutes. After that it should return to normal. If this does not work you may have to refer to the shop manual. Before you go to that trouble, call the manufacturer of the replacement actuator and ask them. Good luck.
