Having a problem with the wipers not working all the time. Without going into great detail on what has happened so far I will explain my situation presently. I've got a 2014 Thor ACE 29.2 on a Ford F-53 chassis. When starting the engine cold the wipers will not come on until the the coach warms up. Specifically, I've noted that the cockpit heater needs to be turned on. Found out that one of the two wiper relays in the engine compartment was bad and replaced both with new ones but the problem persists. Multi function switch on the steering column has been tested and its fine-high beams and turn signals work at all times. Apparently there is a wiper control box located near the floor in the driver's cockpit area. Could this be the answer? Heat blowing on it somehow makes it function? Anyone hear of this issue? Thanks.
