RWD Volvos Have PNP Switch Flashing Arrows Too

MVS member Bob had the common flashing arrow light on the dash of his 1995 960. Flashing arrows usually mean it's the PNP switch.

PNP Switch Flashing Arrow

MVS member Bob had the common flashing arrow light on the dash of his 1995 960.

While looking at the wiring harness connector (8 sockets) that plugged into the PNP switch connector (8 pins), I noticed one wire looked “funny” – and for good reason. It was no longer connected to the crimped on socket connector. I began tugging at these wires that went from the main wiring harness to the connector and several of them were not even connected any longer!

I cut the remaining wires from the connector and examined the connector. It’s a plastic box that has “ears” that fold down over the socket connector that is encased in a short plastic tube within the box. What was astonishing was that most of the sockets themselves had DISSOLVED. This left the wire to be just held against the inserted plug from the PNP connector. As it was driven the wires vibrated away and toward the connector sometimes making contact and sometimes not.

I have been fortunate enough to be able to find replacement sockets at an equipment salvage store, a real good hand crimping tool (Crimper, Ratcheted, AWG 20-18, 16-14, 12-10, ..non-insulated, open barrel terminals $35 – Amazon), clear plastic water tubing (5/16″ OD x 3/16″ ID). I have literally rebuilt the connector block. Car starts and runs great even though this has been a 2 year process with it sitting a lot.
