W900 low pressure buzzer

The door lock actuator (motor) to be replaced.

The buzzer for low air pressure and start up not working, it could be a instrument panel cluster problem. The buzzer could be bad on the circuit board and may need to be replaced.

The interior courtesy light problem could be a bad door switch not giving a signal to the light to turn on.

 

Did you buy the truck blind?

You should have seen a couple of these problems before hand and subtracted the repairs off the price.

 

Door lights and welcome sounds?
I think that stuff broke on my 379 before it was delivered to the dealer from manufacture. You young guys need to toughen up as truckers lol

Just bustin balls

 

my 07 w900 doesn't make welcome sounds.

My door lock acts up once in a blue moon also. It be wise to disconnect the thing before you lock yourself out. Use the key to lock/unlock the doors

Do you have an alarm with door open and yellow brake released? Mine does. I don't know if all that is tied in to one switch. But one switch is all I have in the door.

The buzzers and red lights on the gauges should work below 60 psi.

Don't know about the dome lights. 1 was there. Now both are missing. Neither worked. I have a new dome light setup now. It's wired to the switch. But doesn't work in the middle position so door open is no good.
