940 Estate 1997. Electrical problems

Hello all

Two weeks ago I had a reversing proximity warning system fitted by local "Auto Elec. Experts"

Almost immediately the bulb fail dash light lit and offside stop light found to be not working.

Inspection showed that the bulb fail light was lighting when reverse engaged. Further specialist attention . - they fitted a resistor or something in the circuit and brake light worked and no bulb fail indication.

However, night driving produced another bulb fail warning when going from full beam to dipped, and car was booked in for further attention. But, last night all front lights except full beam, fog and indicators failed! and car had to be breakdown recovered as police banned it from being driven.

Car booked in for "Specialist" attention tomorrow, but they say they have no idea what is going on.

Any experts out there have any thoughts? I suppose all the front bulbs could be actually blown, but at moment I am keeping my hands off, otherwise they will blame me.

I expect that they forgot to allow for the Bulb failure sensor relay(s). The wiring should be before the relays to prevent spurious warnings. Normally there are two reverse lamps, two (or three) brake lamps and four tail lamps fitted at the rear. They just didn't know what they were doing and wired the reverse proximity sensors to the wrong connections. You should have taken it to a dealer or a savvy Volvo owning friend.

All the best, Peter.

Many thanks for comments.

My Volvos have all been serviced at an indipendant garage specialising in Volvo with ex Volvo mechanic.

They recommended I take car to the electrical specialist!.

I have got the impression 'specialist' does not know what is actually involved. Comments like "It cannot be the sensor, must be the car and a blank look.

Will be seeing them today, on the basis of make it work or take it off and refund.

Many thanks again.

If you could attach the wiring instructions to me I can check them out with the car's wiring. Listing the connections they have done as well, would also be helpful.

All the best, Peter.
