Recently my a/c blower motor started acting up. It's very hot and humid here in Miami so I'd like to fix it soon. I already have the relay bypassed from the low pressure switch straight to the compressor, and it works fine. But now, the blower started getting weak through the vents and then stopped altogether. At first I thought it was a resistor or blower motor issue but then I heard the blower working hard but no air coming from ANY of the vents. After sitting overnight, starts working again but the blower starts weakening on and off. Confussing... any ideas? Thanks!
