Inspection Procedure

CHECK FUSE
1. Check whether the regulator switch fuses P FR DOOR 25-amp, D RR DOOR 20-amp and P RR DOOR 20-amp of inoperative seats are normal.
  NOTE:
  - If the fuse for the passenger side door is normal, proceed to (OK-A) . Go to step 2.
  - If the fuse for the rear RH and LH doors is normal, proceed to OK-B . Go to step 6.
  - If the fuse for the passenger side door is defective, NG-A : REPLACE FUSE (P FR DOOR 25 A)
  - If the fuse for the rear RH door is defective, NG-B : REPLACE FUSE (D RR DOOR 20 A)
  - If the fuse for the rear LH door is defective, NG-B : REPLACE FUSE (P RR DOOR 20 A)
