I have a 1990 4runner 4 cyl manual 4wd. About 3 weeks ago the defrost/heater blower stopped working as well as the center console blower. I checked all fuses and I tore apart the dash attempting to to see if there was power to the blower. I replaced relays as well which you can hear flip when you move the control switch. So I know there is atleast power to the relay. After not being able to reach the blower I got mad and slammed the door. Amazingly the fan came on. It ran for a week and both fans are now not working no matter how hard I slam the door.lol Please what should I do??
