So that you know, the overdrive relay is behind the ashtray. Pull out the ashtray, take out the cigarette lighter, pull the face clip off of where the lighter resides, exposing two philips screws, take them out, pull out that panel, and viola, you can see your relays (at least some of them). The tall white rectangle on the RS is your overdrive relay...this is the culprit. Some people on this board solder theirs, I generally replace 'em.

So you know...several customers have said, "I never use my turbo" which starts a discussion about it's exhaust driven, as you as you are creating exhaust, the turbo is working...no, I NEVER press the button on the gearshift...

One customer of mine, with a 1987 Volvo was heading to his in-laws for Christmas and requested quite a bit of service before heading that way. He called to say, "Wow, the car did great! Since it has been so long since I had service I never used my turbo...man, I hit my turbo button at 75 mph and you should have heard that baby scream!" "Scott, your car doesn't have a turbo. What do you mean you hit the button." "You know, Chris, the one on the gearshift." "Scott, NEVER DO THAT AGAIN."

Welcome to the world of Volvo...you'll like it here.
