99 Volvo S70 Directional blinks rapidly.

Question edited for clarity.
Question moved to model category.

This is a strange code that doesn't appear to have one definitive reason, it's a bit of "you have a bit of a problem, but we aren't sure". Just Answer dot com mechanic says it is the MAF Sensor.

Check front signal bulbs.

I imagine that you installed the code in the radio after installing it. Check that you picked up the correct power wire (accessory [power )

On my 1998 S70 there is a rocker switch next to the sunroof and back window and mirror heat below the tachometer on the right hand side of the dashboard. If you have no other way, remove the fuse from traction control on the the main fuse box under the hood on the drivers side. There should be a guide to which fuse is which on the lid of the fuse box.

Hi, I have a couple of questions.
1. were the signals working before you replaced the brake light bulbs, and did you use the recommended bulbs?
2. Do the brake lights work now?

The brakes and signals use the same filaments, so these things are tied together.

use Volvo ATF fluid or Mobil 3309 ATF, the Mobile 3309 may be cheaper.

Sorry for the delay.

Hello Joan,
The climate controls on your Volvo are all electronic at the control end, but likely have little vacuum motors to control the opening and closing of heater valves and air directional flaps in the innards of the dashboard. With the "mature" nature of your vehicle, it is sometimes a cracked vacuum hose or that the rubber end is getting a little hard and now leaking at the nipple where it is plugging into the vacuum valve. IF this is the issue, you MAY be able to here a hissing noise immediately after turning off the engine. Crawl down and get your head (ears) right under the dash. There may be a cardboard/plastic cover plate on the underside of the dash that you have to remove to get access.
But from the symptoms that you describe in your post, "Temperature dial has lost it's clicks"... I SUSPECT that the contacts on the control module may be totally worn out for both the direction of flow and the temperature control. Modules are available on eBay/Amazon (usually used) and it should be quite straight forward on how to remove / replace. The link below provides both links to purchase the control and also some YouTubes on how to replace it.
Hey... do you have a Pick-n-Pull or similar self-serve auto-wrecker near by? Often you can see what vehicles they have on their lot. It appears that s70 v70 and c 70 Volvos from 1998-2000 all have the same control unit. I've also included the part number in one of the photos... do a search for that and you may find more hits.

I hope this helps you Joan!

The bulbs could be ok. That means your car has a short circuit on the left side which is causing the blowing of the fuse every time you intend to switch the left indicator.
