Not sure what year your Zephyr is but most Tiffins have ducted A/Cs and the intake filters are located in the ceiling intake ports. The ones on the driver's side are intake and the ones on the passenger side are the output of the A/Cs. You just pull straight down on the port louvers to access the foam filters. It doesn't sound like filters are your problem though - more likely the starting capacitors on the units.
