Please fill in your profile with the year and options on your Q (e.g. if it's a touring model, active suspension, etc.)

It's also a good idea to show how many miles are on your car.

Could be a variety of problems such as stuck defective relay, defective coolant temp sensor, defective A/C triple switch.......follow troubleshooting procedure in factory service manual to pin down exact cause and its remedy.
