Hello All, hope everyone is doing well.

1975 Coachmen built Royale, I was having intermittent issues with the motor blower working on high, works on low but appears to be the same speed regardless of low - med - and med high.

If I moved the switch from side to side it would work on high speed and sometimes while positioned on the high speed but not working it would sometimes begin working while driving.

Now it's not working on the high speed position no matter what I do, however, it still works on low speed regardless of the switch position..

I removed, cleaned and replaced the connectors to the relay.

I did some research and it sounds like it's the blower motor switch, I think?

Can anybody confirm the switch part number is the GM AC Delco 15-7812 OR should I be looking for something else?

As always your opinions are welcome and appreciated.

Regards,
Mike
