On many occasions when the A/C has decided to work, it starts out blowing on high just like it should. As I drive, the air output will get slower and slower till the point where cold air is just barely coming in but the A/C controller still says it'* on high. Would this still be just the blower motor?
Hmmm Multiple answer question...
The only thing that forces airflow thru the vents is the squirrel cage blower.
The blower is (of course) powered by the blower motor, and it'* shaft, rides on lubricated bushings.
The cage itself is usually bulletproof, unless it'* been in a collision.
That leaves the motor, and the bushings.
Starting with the easiest.... the lubrication gets dirty and sometimes,
will stick, or cause excessive drag on the shaft, slowing it down.
The other thing it does is it will be blowing on high, and sometimes when I deccelerate the air output will stop and once I accelerate again, it comes back on again. What could be causing this?
Thanks in advance.
I feel from your description, that this is the case. when you accelerate the cage and shaft are forced rearward, to where the dirt and gum is less "Sticky" ( for lack of a better term) and when you brake it returns to the more resistive area. pull the motor and cage, and clean the shaft with a good degreaser, dry , then add a few drops of light oil to the shaft where it touches the bushings. You'll have to disassemble the motor to get to the rear bushings.
