My explorer 98 seat lumbar does not work. When i push the switch i only hear a motor noise and nothing happens. Any ideas how to fix that?
Thanks

 

Welcome to the forum!

Since you hear the motor noise, the compressor is apparently trying to run. If you press the button to deflate the lumbar do you hear any faint hiss? If not, there's a good chance either the lumbar bladder has a hole or the hose to it has a leak. Until you do some more troubleshooting, the only fixes that will be offered here will just be guesses.

Thanks for reply
Only the inflate button works and i can't press the other side of the button to deflate. It fells like its deppressed already. Maby the switch is broken i am not sure

 

According to the factory diagram for the 1998 power lumbar, the deflate position of the switch does not involve anything electrical. In the deflate position the "fill" tube of the lumbar bladder is just vented to atmosphere. Since you are not hearing anything when you press deflate, the bladder is likely not filling. Since the compressor seems to be running, I'd guess you either have a hole in the bladder or the switch to switch the tubes between the compressor and the vent is leaking.

thanks for these valued information. I will check the hose between the compressor and the bladder. But do i have to unbolt the whole seat to check that or i can work around it while its still bolted to the floor?

 

Well, I've never personally had the seat from a 1998 apart so I'm not sure what you can reach with the seat swill in the vehicle. The only seat from an Explorer I've had apart was for a 2004 Mountaineer and I removed it so I could get to the seat heater pad so I didn't fuss with it much while still in the truck.
