i had the same problem there is a pcb board under the dash that needs to be replace. i got it at the dealer for 75.00 bucks.
what is problem if fan works
1,2,3 setting dont work at all. 4 is intermittent. The vents all change fine and the heat adjustment changes fine. Its the motor speeds that dont function properly
