Hey Sal, it's no problem, I worked on these Volvo's for many years and I enjoy helping. It's very difficult to make assumptions when repairing these types of issues, especially when the cost of being wrong can be very high, you're smart to take it to a shop to have them check this out.
My suggestion is you find a good Volvo Independent shop in your area. The techs who work on these everyday can and will be better suited to address these types of issues than others who don't. This is a bit of a generalization, and there are great techs at just about every shop but these vehicles do have common issues that a Volvo tech will have addressed many times. You'll definitely want a good Volvo tech when those door window regulator issues occur too!
Good Luck!
