Working on a 1989 Mercedes 560SL. We diagnosed an electrical issue with the dash light that was causing the dash lights to only light up when the right turn signal is on. We also diagnosed an issue with the left window not going up. We diagnosed an issue with the a/c not getting cold. We repaired the wiring to the right front headlight that was causing a short and back-feeding electricity in other circuits, we replaced the turn signal relay and hazard flasher switch, we replaced the left and right window switches, we replaced the brake fluid reservoir grommets due to leaking brake fluid, we replaced the a/c condenser because it was leaking, and we fixed an issue with the removable hard top that keeping the lock from disengaging and releasing the top so that it could be removed.
