asked by on

If the fan goes to 100 percent but does not reduce speed then the fan control module assembly needs to be replaced as an assembly as no parts are serviceable. A bad power steering pump may pass debris into the fan module valves and cause them to stick. The fan valve is not serviceable and the fan assembly needs to be replaced as an assembly. If you want this looked at first, a certified technician from YourMechanic can inspect your A/C system in order to make the correct repair.
