All Turn Signal lamps solid, not blinking 2000 V70

Post by AnyMajorDude » Sun Mar 03, 2019 8:48 am

All turn signals are solid not blinking, front and back, when the turn signal is turned on, told it was an occasional problem, now happening consistently. Switch? How confirm?

White Volvo V70 year 2000.

THanks in advance.

Try your hazard switch. If all 4 corners blink, then there is a problem with the stalk switch. I suspect the relay, part of the hazard switch, is the problem.

On turning on the hazard switch, all four lights go on but do not blink.

Pulled the hazard switch out, disconnected, used an emery board to clean off the contacts, reconnected, and all is working.... for the moment. But....let's go for a drive and see....

It is working then not, then with some fiddling of the hazard switch, working again. Does the relay in the hazard switch cause the clicking sound coming from the hazard switch when it is working properly?

The relay is faulty and as far as I know, it is not repairable. Look on Ebay or parts suppliers for a replacement.

What's your bulb situation? On older cars the signal flash rate is tied to current through the circuit. The current heats up a spring-steel reed in the flasher, which "snaps" into a position that closes the circuit, sending lights to the bulb. The current through the bulb is lower and the Reed cools down, snapping back to its original position, where it heats up again, and the cycle repeats. This is the source of the snapping sound. Nonstandard bulb arrangements (LEDs, multiple bulbs wired together, etc) can cause erroneous behavior. This is also why signal lights flash very quickly when a bulb is burned out.

Not sure if something as new as a 2000 V70 still has that arrangement in the flasher or if it would be something smarter, but if you have something unusual going on with your flasher bulbs, you may have to tweak them so current flow through each bulb resembles the stock bulb.

EDIT: Pretty sure I have it backwards - current flow due to the lights causes the reed to snap away and open the circuit, and the reed cools down while power is not being applied. This is why the first click of a turn signal in an old car takes a little bit longer - the reed is heating up from ambient temperature. I can't recall if my V70 does that so maybe that technology was long gone by the time of the P80 cars.

I had this problem some years ago. Hazard switch was faulty. But after taking it apart and inspecting, it looks like there are some cold solder joints on the PCB. It worked after reconnecting the plug, so I guess it's repairable.

My 1999 diagram shows independent turn signal relays 10/15 and 10/16 , which I doubt would independently fail together. I think your 2000 shares the same chassis as late P80 models.

Find the wiring diagram and post it up for dissection.

‘98-‘00 share the same turn hazard system.
All flashing is controlled by hazard switch that
is a known point of failure. Common issue is
that turns are solid, but hazards still blink.

In either event, repair or replacement of the
switch is the usual solution to no-blink issues.
