any way to modify the hvac system for a stronger blower motor?
Every thing is in proper working order, however as im sure many of you know the blower motor in these cars even brand new replacement is terrible compared to new cars like the brand new cars I drive everyday.
Is it possible to fit a stronger blower motor from a different vehicle? or modify the stock one?
using the heat or a/c is often useless because it doesn't push any air than I could out of my own mouth.
any help appreciated..thanks

Sounds like something is wrong with your wiring, the motor or the ducting has a big leak somewhere. Mine all blow strong especially at full blast.

I've noticed the same thing. My ac blows cold but cant cool off a car on a 100+ degree day if it blows weak. Hopefully there is a similar motor out there

I have had similar concerns, I wonder if its because our blower is fitted outside the cabin. And how long would a blower motor made for inside the cabin last on the outside

If I remove my ac and the resistor can I use my blower on high only for defrost.

Is it possible to get a resistor from a newer say later 90's gm product and it give the motor more kick?

Re: any way to modify the hvac system for a stronger blower motor?
That might work for for the lower speeds but I don't think it will increase overall power. If there was a way to lower the internal resistance of the blower motor itself.....

I'm actually really satisfied with my A/C, it works better in the summer than my '09 Silverado lol
