Hey everyone I'm having Trouble figuring out what could be the problem? How do I replace the blower motor resistor? I got 1 2 3 4 5 all good speed wise. I can hear the blower motor is on but when I put my hand up to the vent on low medium and high. I can't feel. No heat coming through the vent just barely any heat is coming through the vent on high. It feels like it's on low, but actually on high what could be the cause of? Hardly any heat coming through the vent?
