SOURCE: blower motor

I say it might not be the blower motor but your on the rite track!good place to start sounds like a loose wire check under hood on passenger side to see if your blower resistor speed switch is plugged in or it might been in passenger feet area above toes in heater box! I think passenger feet area might be the spot your looking for! a v shape plug! i think you will find it no problem!hope this helps

SOURCE: heater blower motor works intermittently

I would replace the blower motor, this sounds like a motor brush problem inside the motor itself.

The heater fan dose not come on some time when driving hit a bump on the road it comes on .


Most likely the blower motor has excessive wear and the brushes which contact the armature are contacting more than one pole at a time, hence the intermittent failure. Hit a bump, or hit the motor, and it'll suddenly come on... Pretty typical really.

Either its developed the same fault or the fan motor bearing has failed, needs greasing or, if there's a belt, the belt is slipping.

My blower motor works intermittantly, if i hit a bump in the road it may go on or turn off


hi, there a few things to check. is the fuse loose. or the heater motor connection loose. the trouble is the heater motor is normally in the middle of the dashboard. but sometimes if you take out the glovebox it maybe behind that. check fuse first. gerry
