The rear blower motor is going out. To use the rear A/C I have to bang the rear cargo area with my fist and the blower motor will turn but it very slow and then it comes to a complete stop. I am going to replace the blower motor. I removed plastic paneling and need some help on disassembling the rear A/C housing to get to the motor. The housing is held together with screws but I can't access the screws against the fender. What is the best way to get the blower out? Also, can I do it without removing the A/C lines?
