Nipper, if you have a truck it could be located just about anywhere. The blower speed switch was sources by your body builder. They would be a good source for a part number or information as regard location.

They no longer make this plus they sold the company.

Nipper, This may or may not pertain to your coach but on my 2001 Airstream Land Yacht the blower hi circuit is connected to the COACH batteries while the low and medium speeds of the blower are connected to the CHASSIS battery. How do I know this? I tore the dash of my MH apart trying to find out why my Hi speed blower was not working. I finally found the correct wire and it was connected to the COACH battery circuit and I had the COACH batteries disconnected by the switch near the entry door.

Trail-Lite was bought by Monaco Coach Corp, who then went out of business. Their successor is Monaco LCC, owned by Navistar. Their service dept may be able to help you. Also, lots of coach A/C units are made by Evans Tempcon, they have some manuals on the site as well that may help, and their tech support has been helpful to other posters on this forum.

I found the ristor pack all of them test OK. It appears that only thing not working is Hi speed. Switch shows voltage going out.I need wiring diagram does anybody know where to get one ??

nipper310, my high speed blower fuse is an 'inline fuse', 30 amp , I think, and it's in the engine compartment, drivers side , on the firewall.
