what causes a/c heater blower motor to quit blowing under engine "load"?

Asked by Jun 28, 2016 at 05:31 PM about the 2000 Dodge Ram 1500 2 Dr SLT Extended Cab SB

Question type: Maintenance & Repair

blower works on all speed settings, for both heat & A/C, but under acceleration or particular strain/load on motor, it will quit blowing. let off the gas a little bit, and it will start blowing again. very strange. was also battling a wet passenger side floorboard, thought a clogged condensate line might be culprit for both issues, but not the case...  anybody else experience this?

quits blowing or stops pushing air.??? check for a vacuum leak...

Run that scenario again,and listen if the fan actually stops running or if the air ducting flaps are instead moving due to lack of vacuum pressure at open throttle. Although the actuators are electric driven, there is still vacuum at play in the HVAC system. Every car does this, some worse than others.
