I have a 95 mx6 which has had an intermittant problem for a while. The switch for the fan/Air con doesn't always work hence I don't get ventalation sometimes. I've had the actual switch check a couple of times and seems to be okay. Sometimes when you start the car up it wont be on, then 10 minutes later it will turn on. had it looked at a couple of times for the switch or loose connections but no one has been able to fix it. Any suggestions?
