Customer Complaint

Power seats and mirrors are no longer working.

Problem Summary

Cannot adjust the two front seats and mirrors. The engine has had the engine replaced because cannot source or repair the transmission so a Toyota 1KZ-TE with transmission has been fitted {{pic1}}, new modified engine mounts and exhaust system. The inhibitor switch is missing. The airconditioning system was modified to fit the Toyota compressor. Now runs a vacuum pump for the brake booster. Power steering pump modified and speed-sensitive steering no longer works. At high speed, the steering is not firm like it should be.

Power windows were repaired recently with some parts from a Toyota. Can see many wires chopped and some Toyota relays fitted in the boot where there are several modules.
