part # for dash air / heater controls?

[ek_lektro]

Now that i’ve got the dash air working in the Eleganza II, its time to replace the temperature control and selector switch(es).
I jumped the gun and picked up the Wells SW1873, by accident; as it turns out that this since this is just the up/down switch for the blower motor. But i don’t see any part # listed in the Parts Interchange for this air/heat selector switch (the 2 horizontally sliding knobs)
(I remember changing one when i first got my coach.. 18 years ago!)
Thanks in advance, cheers, and stay cool out there!

You will have to get that from a parts coach.

Not necessarily. He can almost certainly refurbish the one he has. Others have done theirs.

The temperature slider just connects to a cable that opens and closes the temperature door.
The function selector rotates the wafer with the holes in it that determines which actuator(s) has vacuum AND enables the fan and/or compressor by
making electrical contacts.

Here are the links for howtos that I sent to Bob D. a day or two ago:
