Saab window off track

The first window we actually took to the dealer–thus the $750. My husband tried to fix the second one himself but gave up so we took it to our regular mechanic who said he would do any kind of service work on a Saab just not any engine work. So he is actually new to Saabs and since he is a GEM he did it for only around $300–he got me a used motor. Saab people, don’t think you have to go straight to the dealer or Saab mechanic for everything! This guy changes my oil too. Your reply was very enlightening. Thanks.
