Toyota MR2 Mk2 SW20 Electrical faults | Interior | Door wiring | Harness | Diagnostic & Repair Pt 1 

Cracking stuff, it's a lovely motor.

I replaced 3 wires already, waiting for the next one to break. The others did look good. My problem was the speaker and the right mirror malfunctioning. (Searched first on the wrong side (right door) (LHD) but the problem was actually on the left side (that door open/closes most on my LHD) I Would have rather bought a completely new replaceable part of the cable that goes in the door.

Electrical problems in Toyota? Unbelievable, someone must have done something wrong before! Got same year Celica and everything works!
