Could use a little help on this . . .

I have a 1993 240, manual trans. Under 100k miles.

I noticed that the turn signals weren't working today.

Replaced Fuse 5.

Turn signals work (front and rear). Power Mirrors work. BUT, when I shift into reverse, the fuse fries instantly.

Circuit boards have been replaced in back . . .

Bad reverse light switch?

Any thoughts?

Appreciate any feedback

ALEE and ART

Glad I didn't bet against you guys(and your 99.99% probability!).

You drilled it- bad wire to switch. Had a local shop check (and repair) it.

I'm going to talk to the mechanic when I pick it up and find out whether he got to it from under the car (and if so, if he had to do any mechanical gymnastics to get to it) or if there was another approach.

Thanks again for the quick responses - looking forward to having directionals back this afternoon.

Now on to the horn . . .

Probably bare wires at the switch.

Post Back. That's whats makes this forum work.

Thank you for the quick response aleekat. Will let you know how it turns out.

"Probably bare wires at the switch."

And that probability is about 99.99% Don't envy M47 owners for that job, but the AW-70 solenoid is no walk in the park either.

What do you call a dinosaur with an extensive vocabulary? A thesaurus.

AB -

Thanks for the vote of confidence in Alee's response. Sounds like that's about the first place to start.

How bad is it?

"How bad is it? "

I've not had the pleasure, but you can read many posts complaining.

The wiring used to reach the backup light switch on the top of the M47 has a high strand count to survive the flexing between the body and the transmission. The insulation attempted this flexibility too - it is silicone rubber. Unfortunately it did not last as long as the car did. So, you could do some digging in the archives, or maybe someone who's recently done it will see your post and tell you about whether you should patch it up with auto-store wire and auto-store crimp connectors or see about getting a genuine replacement harness. And if you think I'm recommending one or the other, I am not. Someone will always come along and tell you how they could have done it better than the engineers at Volvo. Or on the other hand, you might just crawl under there with a flashlight and mirror and decide you will invest in a bottle of liquid electrical tape. :-)

I'm reading a book about anti-gravity. I just can't put it down.
