W22 Workhorse evaporator coil part number

I think it must be a secret part number
Is there a number other than workhorse ?
I can't even find workhorses
Any help please ? A 2002 model with a 8.1 vortec

Workhorse did not supply the evaporator coil. they supplied the compressor, dryer, and condenser. the rest was up to the builder of the RV.
Look at the firewall from the front and you should see a sticker that says who supplied the rest of the system.

Welcome to iRV2 .

Mike is correct , Workhorse didn't provide the evaporator , the coach builder , built the dash portion of your air conditioning system , with a kit from a supplier , such as ; Evans/Tempcon , or Denso .

Look at the housing for the heater core/evaporator for a clue to the supplier .
The different suppliers of the parts is the biggest headache in servicing motorhome dash A/C units.
