Joe, Be advised on 94-95 Alfa 164 there isn't a brake light relay (only on 91-93 models). Is your dad's LS automatic? If so and gear shift will unlock when brake pedal pushed then fuse and brake light switch good. If you have to push manual override through little hole in console side carpet then potted shunt in switch wiring probably bad and needs to be cut out and wires spliced together. If manual 5-speed you don't know if shunt is bad. To test switch you have to bypass shunt but first to see if shunt good locate white-red trailer wire under battery cover in trunk. With pedal pushed if you have power there then fuse, switch and potted shunt good. If not I would bypass shunt and try again if now power at trailer stop light wire and still no brake lights you have to trace wiring back through instrument cluster as it feeds the power to L/R and center brake lights. Much different system than the earlier 12v 164s which do have brake light relay but no potted shunt. Alfisto Steve In a message dated 2/24/2011 2:32:51 A.M.

(The bulbs that are also used as turn signals still function in that capacity.) Are there wiring diagrams available for download anywhere? I talked my dad through measuring resistance across the switch, and apparently it's normally closed, and then breaks the circuit when the brake pedal is released. (Is that normal among modern cars?) So it seems like the switch works, but there's no voltage being applied to it. (The fuse is fine.) Is this a common problem?
