Blower motor switch

Try Dorman 599-5000...have the same problem myself and I'm not paying $600 for the whole thing again

 

Try Dorman 599-5000

 

That's the switch!

I ended up finding a whole used control panel on eBay for 150 so I bought that. But if I ever need I switch again in this truck or the sister of this truck I'm glad to know the part. Hopefully if someone else needs that switch they find this thread instead of bending over to Peterbilt for $600

 

Had this same problem in a 2013 peterbilt but also need the connector that connects to the back of the blower motor switch.

Connector is made by Delphi and connector experts in Chicago sells it for 75.10 plus shipping if email them and say need connector for the the dorman switch number 599-5000 they have it and will have it shipped out to you the same day.

In case anyone also needs to replace the connector along with the switch.

 

Dorman 599-5000 should do the trick. 8-Pin Connector piece that plugs into it is Peterbilt OEM 16-05702
