I've got a 2007 Pathfinder se with the automatic temperature

Customer Question

I've got a 2007 Pathfinder se with the automatic temperature control option. My climate control blower works sometimes and sometimes doesn't. I replaced the fan control amplifier last night. It worked, but this morning it stopped blowing again. Any suggestions?

Hi there,

A common issue with these is the blower motor relay. It's located in the relay box under the hood. I would try changing the relay and see if there is any improvement. If not, then you may need to get a shop involved to check the sensors involved, but again, the relay is a common issue and may be a vary inexpensive fix.

I am sending along a diagram of it's location in the relay box to help.

a bad relay can cause it to work intermittently? I would think a bad relay would cause it to stop working all together.

Could the cabin air filter cause any problems like this?
Expert:  Mike V. replied 1 year ago.

A bad relay can make it stop working like this. A cabin air filter will not stop it from blowing. Lack of power will which is why the relay causes the problem sometimes. It's becoming a fairly regular issue on these. Sometimes stopping the blower completely, then after restarting the vehicle taking some time to come on even though the blower is suppose to be on. The relay sometimes makes contact inside, and sometimes not. If I am right it's about a $6 fix, if not it's not a huge investment prior to finding another issue.

I'll try the relay in an hour or 2. I'll let you know the result.

Sounds like a plan.
