Circuit board medics. Not local but got me my cluster back in 3 daysFinding one in junkyard would be like finding gold. Cash for clunkers pretty much crushed most vehicles from the 90s. None available thru the yards I deal with. Checked around but didn't wann go that route anyway.
I haven't pulled the PSOM off the cluster to look at it.. I've just checked inputs and outputs. I have to give customer a price before I go any further.
I'm 100% positive the problem is in the PSOM after checking all the wiring. All good to the PSOM but no output from PSOM to PCM. It's a known problem and back in the 90s Ford even issued a TSB (technical service bulletin) to address the issue with an updated PSOM
Basically the speedometer works in cluster but not sending the converted signal to PCM. PCM sees no speedo and basically doesn't let the transmission shift gears.
Think I'll call a couple companies I see online and inquire. I was just trying to minimize the downtime from shipping to and from
