Can you help me troubleshoot my 2002 Pathfinder that is having vent control issues?

Answer by  Rosem (22)

Its most likely the heater controls. The headunits are complicated and can fail. You may want to look into the actual mechanics that control the operation of the vents

It sounds like to me that your blower motor has gone bad. It can also be just the blower relay. I would check those first.

Your blower motor may have gone out. It may also be a blower relay, check them first. Your vacuum hoses might have some holes in it.

Yes.Vent control issues are usually with the vacuum hoses.Locate the hose first..usually it should be between the air inlet and the engine throttle and once you locate the hose check that thoroughly for some holes in it which is the major issue.Make sure the vacuum hose is connected the 2 more connectors in your AC panel are connected as well.

The 2002 Pathfinder isn't known for its vent control issues, but it's still not an uncommon problem. I can help you troubleshoot the issue if you describe the problem.
