Toyota heater motor fuses
Intermittent cold air or warm air when not needed
Toyota Highlander 2005 AWD 6 cyl. During winter intermittent cold air, during summer intermittent warm air come up. Working solution turn the nub one direction or another. Driving over a bump brings the cold air also. What could be the cause?
Re: Intermittent cold air or warm air when not needed
You might want to start by checking the connections on the back of the HVAC control head. Also check connection on the temp actuator. Normally, a problem like this is usually a bad control head or actuator, but since it seems intermittent and acts up over bumps, it may be a wiring problem.

Re: heatet motor
according to the wiring diagram, you have a fusible link that goes to the heater circuit breaker. from there it goes to the heater relay.
you have a 'gauge' fuse 7.5A to the relay too.
you have two wires to the heater blower motor. one blue and red and the other just blue. with the key on turn the fan switch where it would normally on. check the blue and red wire for power. if you don't have power look at the relay, circuit breaker and fusible link. If it does have power check to see if you are getting the ground signal from the switch and blower resistor
