blinkers work, no blinking noise inside the cabin though
My wife came home yesterday and said her blinkers are not working on the XC70. I had her test both left and right and the emergency while I looked at all four corners of the car. They all work however the dash arrows do not light up nor do we hear the clicking noise when it's blinking noise from the dash.
Any ideas?
Cleaning the turn signal switch on a 2002 V70 XC70
I was experiencing the intermittent flashing/pause/flashing when signaling for a left turn and just found this thread...which inspired me to remove the switch and take it apart. The cleaning procedure I came up with was inspired by my experience with slot cars when I was a kid. I just tried it, reinstalled the switch, and it works swimmingly! No more intermittent flashing.
I followed the VADIS removal instructions from BillAileo's post earlier in this thread.
It was easy to get the switch out. I brought it into the kitchen where I had good light and a clean place to work. Remove the circuit board from the back of the switch body using the single phillips screw. Keep the circuit board side up so that the small which plastic contact slider doesn't fall out. Nothing will fly across the room when you pull the circuit board off...just go slowly so you don't lose the white thing.
There are two groups of contacts (and two functions) managed by the contacts on the circuit board: 1) Turn signals, and 2) high beams.
I used a pencil eraser to clean the contacts...
I also very gently cleaned the contact points on the contact slider (this small square white plastic slider handles the turn signals) and even more carefully "bent" them outward to force a bit more pressure on the circuit board. Don't forget which way it goes when you put the slider back in the switch body. Or use these pics as a reference.
You can see the difference between the contacts I cleaned (for the signals) and the ones I didn't (for the high beams).
Make sure you have the contact slider in place properly, reposition the circuit board and tighten the little phillips screw.
As mentioned by others, be careful replacing the switch as these little pins are fragile. On my 2002 XC70 the switch body goes straight in and travels on two plastic "rails" on the top and bottom of the switch body.
