Sounds like there might be a loose connection at the blower motor itself, or it could be an internal fault inside the motor. The blower motor should be on the passenger side floorboard underneath the dash. If you have the switch on high and smack the motor then it will most likely come back on. You can either by a new blower motor from a parts store, or go to a junkyard and risk if that one even works.

My heater blower dosent work uless i hit a bump or something and if i hit a bump it gose back off


This is often caused by a lose cable to your blower motor or your blower could be going bad. You can this by removing the cover underneath the glovebox. This will give you access to the blower and harness.

My heater in my 2002 Hyundai Accent quit blowing. I took the dash out where the stereo is to see what I could find and my dash lights quit working. I thought I had a lose wire of some sort because...


what you need is a new blower motor. It is located under/behind the glove box. The reason that it comes on when you hit a bump is because it jars the brushes in the blower motor to make better contact then when you hit another bump it losses contact.

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
