customer's car, i am not very familiar with Volvo's.
where is the speed sensor? he had me put in a used unit (cluster)
he had purchased for a wrecker. still intermitent, but now odo does
function when the speedo does come on, which isn't too often.
i took apart old cluster and resoldered all connections and
re crimped some of the connectors.

does anyone know how to check these sensors with a multimeter?

Thanks guys!
