I had the car in with the dealer (Manhattan Volvo) due to a check
engine light and an inability to find a shop to trust in Bayonne, NJ.
I was an aircraft mechanic, so I can work on stuff but really don't
know my way around newer cars. I had them look at this and that, and
they are fixing an emisions problem. Service writer said the parts
all had to come from the factory (except the emisions valve). They
called back and quoted a lot more than the car is worth for parts.
And that is the first time I have ever seen a shop manager in a suit
(too big).

I looked on the web and I think the seat cables are something I can do
myself. I also strongly guess that I will have to do them quick, as
Manhattan Volvo will probably re-assemble the seat out of position.
Any source on the net that people favor?

Also need sunroof selector gates.

This may help as to the "how."

As for "where:" consider a wrecking yard.

And what do you mean by "cables?"
