I have an 03 cooper s. The cooling fan does not run. Yesterday I turn airconditioner off and on several times and got the fan to kick on for a few seconds. What controls the cooling fan. Whatr switch or thermostat causes it to come on. I know it should be on all the time the aircxonditioner is on. Also underneath the motor is an auxilary cooling fan that kicks on to help cool motor. I cant find a replacement because mine is going out. where can I find one at.
