I have a 1994 Winnebago Adventure. The in-dash heater/defroster/AC will blow for about 10 minutes (until it gets up to temperature) then it will shut down. After about a minute or two It will act like it is trying to come back on (short bursts of air) two or three times, then it will run again for about a minute and keep up this cycle until it is turned off?
Any help??
