any help here? after i shut off my car my fan will continue to bliow until my battery dies. while the car is on the fan settings and blower speed are accurate, the only problem is after the car is shut off, it continues to run. any ideas?

also, any idea what the indicator "trans failsafe off" means? it pops up once every 30 drives or so. when it happens the car slowly gets dim until it dies while driving. after i wait ten minutes or so and restart, the indicator lights go off and its back to normal..

thanks guys.
