1998 s70 headlights, turn sigs, shift RESOLVED relay 106

Post by mar601 » Thu Aug 08, 2013 10:07 am

New ignition swich, new flasher, ALL fuses are good, headlight lamps are good.

No turn signals but hazard flashers work.

No headlights but have parking lights -- when I turn on headlights, the dash background lighting goes off as well as the headlight dash indicator. (indicator and backlighting fine with just parking lights on). Bright beams work fine. Seems like I'm drawing a lot of current when turning on headlights? (radio dims a lot etc). Battery is fine and getting 14V when car is running.

No shift lock. The shifter is free to move when driving and the button doesn't lock it.

ABS and TRACS lights are on (but may be unrelated -- however have a rebuilt module in there and no problem for years).

Maybe someone knows what's going on ? THANKS so much.

It still sounds suspiciously like an ignition switch problem. Does anything work right if you jiggle the key a little bit?

Otherwise, possibly a low voltage issue causing all these seemingly-unrelated issues. What's the alternator charging at, how old is the battery, and how well is the battery holding a charge?

as I mentioned, just installed a new ignition switch and connector is fine also.

other than the relays in the engine compartment, are there others? I just read about some relays inside under the dash? '98 S70

Yup, but is the lock part of the switch (ignition collar) sticking the switch in the wrong part?

There are relays under the dash (crawl in look directly up by the brake to the right and you'll see em), but each one has its own purpose (wipers, alarm, etc) and I don't know of any one relay where all these tie together.

when I replaced the switch, didn't touch anything -- the flat side of the locater was facing down -- switch works fine.

haven't tried replacing the headlight relay, just ordered one -- that relay is common to both the headlight and turn signal circuits so fingers crossed.

Do you have a tow bar? If so, unplug its connection and see if that helps.

You may find a problem with the 106 overload relay:

Swapping it with 105 should reveal if 106 has bad contacts.

Installed headlight relay -- still no luck.

So now on to the headlight switch -- now I just read it was recalled? Even with the headlight relay pulled I get the same result, no headlights or backlighting -- so obviously it wasn't the relay.

No jiggling of the switch make a difference either.

Scratch that !

You're a friggin genius -- thank you so much man.

I didn't see you had posted a drawing of relays 105 and 106 and you hit it on the head ! Damn it feels good to have this working again. "Overload relay huh"? I wonder that it's function is?

Anyway -- what a great forum -- thanks to people like you. !
