Need a little help. My excursion fan keeps chaging speeds by itself. whent eh a/c mode is on AUTO, the fan speed chages up and down every few seconds. just started doing this any ideas?

Strange, my Ex fan speed appears to only change when the ECT reaches certain temps. The fan runs low (4-500rpm) until the temp reaches ~209 and then it goes to a mid rpm (~1500). Once the ECT reaches ~218 it kicks into high, ~2400 rpm. It seems consistent in those ranges having pulled my camper in hilly areas on hot days.

I think PDCPAT is talking about his blower for the heating/air conditioning inside the truck. You're talking about the engine fan.
Unfortunately I don't know much about that system.
