Weather turned cold overnight. This morning upon starting up the car (1998 V70 AWD, bought about 7 weeks ago, 158k miles): a flashing snowflake icon was showing on the instrument panel and the S-E-W row of push buttons just aft of the gear selector (auto. trans.) was lighting up its small lights in a cascade effect. Upshift icon on dash is also lit (flashing lit? will check asap, am away from the car at the moment.)

Is this a faulty PNP switch?

Bit of added background: transm. was briefly stuck in winter mode on this new (to me) car a few weeks ago, I rowed the gear selector then and got the mode back into the Sport-Economy modes.

Also relevant?: car gets its best gas mileage (27-29 mpg) in Sport mode and seems way below that mileage in Economy mode. Wife and I both thought E mode was returning something like 15 mpg (!) and we switched back into Sport after using apparently 6 gallons to drive ca. 100 miles in E mode.

But car is really stuck in Winter mode at the moment. Left the car on the street just outside our driveway and am driving my '90 745T auto this a.m. Sorry for the added detail this post.

Take PNP switch out, open, clean, repack and re-install?
