Help!!! My S70 signal lights & hazard lights are busted! When I signal left or right, the interior & exterior light bulb stays on & doesn't do that clicking sound (i.e. on & off). I checked and all the light bulbs are fine. When I press on the hazard light button below the stero system, nothing happens, no flashing signals (doesn't stays on like the left & right signal) or clicking sound. I believe it is the "clicking" part that is broken (sounds like it is located below the stereo system), don't know what it is call or how to fix it. Please help! Thank you.

I have a 2000 V70. If the interior is similar to your S70,98, the signal module is just above the ashtray, the hazard light button is part of the module. The module can be removed after undoing two screws holding the base of the ashtray. The module is combination of your signal and hazard electronics, and can be felt in the space above the ashtray after the astray is removed. The hazard switch button is attached to a switch which forms the end of this module. The module is a lightly pressed fit, and can then be pushed out towards the interior of the car. The module is full of electronic components, and cost about $200! Often, it is not the module that is at fault, but the contact with the wiring harness is at fault. I cleaned the contacts and sprayed some cantact cleanser/conductor spray (I used a spray call Corrosion Block, but I think WD40 may work) on the plug and it worked!


Good luck.

Thanx for the info, I will try that later today to see if that will fix the problem.

At the mean time, something weird happened to my car yesterday & today. Here is the story: so I thought my hazard lights weren't working and was showing my friend how busted it was by pressing the button on and off and accidently I left it on before heading to bed last night (can't tell cuz the lights don't go on anyway). When I woke up to go to school this morning, I saw the front signal lights flashing weakly. In my mind I thought "oh no, it is not going to start because the battery is drained!!!" And I was right, the car didn't start because my hazard light delay/switch decided to start working in the middle of the night. How strange!!! So I jump started my car & went to school, but didn't really get to chance to drive around to charge up the battery. However, the hazard light & signal lights started working again!!!

So after an hour or so I try starting my car again, didn't start! So I tried jump starting it again (but my gear box was in neutral). It started easily but then I relized all the dash board displays weren't working (i.e. odometer and all the gauges) and all the warning lights stayed on (i.e. low fuel, cooling fan). I didn't bother with it & drove on a highway for 15 minutes or so to charge up the batter this time. Afterwards I turned off the car and tried restarting the car again and it was fine. However, on my way home the hazard lights failed again while I was driving. I gave up on it and went inside for lunch. Later on when I start my car again, the hazard lights were working again!!! I am so confused, feels like the car is playing a trick on me...

While I usually confine my posts to RWD, I've seen this one before, many times.
Your ignition switch is sticking. Common to all 850 and 70 series.
Eventually if it persists the electrical part of the switch will need replacement ($30-something for the part). You can confirm that it's this if you hold the key when starting the car- release it just to the point where the starter is not engaged. The ABS light will stay on among others, and the accessories will not work. If the key is nudged back to the normal "ON" or II position, you'll have everything working normally.

Good luck with it....

The hazard relay is also used for the turn signals. Sounds like it
failed. Search on "hazard relay" (below, to the right) to find other
psosts with more details. The problem is not uncommon.

As I recall, the relay is behind the ash tray near the radio (but don't
quote me on it).
