Title: 2008 Marquis dash air evaporator
Post by: Kathleen Schell on June 15, 2023, 10:24:18 PM
While having my seized dash A/C compressor replaced the technicians noticed the evaporator had a leak due to oil dripping off the unit.  It is not easy to access any part number to get a replacement on order.  Has anyone replaced their evaporator and have the brand and part number for the evaporator?  Apparently not many of the units with split (pilot/copilot) controls were produced.

Even if the forum could provide an answer the result could be different on your coach.  Suggest you stop by a shop and have them crawl under to verify the part and mfg.
Just FYI.
The seized pump may indicate a plug caused by the drier failing.  The desiccant beads burst and travel through out the system blocking the evaporator and high pressure valve.  Had a shop explain all this as they were using brake cleaner to blow out both lines open on each end. 
Good luck

Keith is right these coaches are seldom exactly the same as the factory used available parts at the time of production.
The only way to be sure you get the right condenser assembly would be to check first for a part number if there's still one on it or to take measurements of the old one and contact a good A/C supply house.
Many of these coaches where fitted with systems produced by ACME or EVANS
