Maybe a bad/clogged heater core. I'm not exactly sure how the Expy's system works, but on past models, there is a valve in the heater hose that blocks hot water from entering the heater core when the heater is not being used. Maybe this valve is corroded closed, etc.

Since it started doing it AFTER it was worked on, I'd check real close in the area that they were in for loose or broken vacuum lines or electrical connections......
