Volvo Repair: Windshield Wiper Motor, windshield wiper motor, wiper arms

Question
<font-size=10+> <b> 1995 940 (not turbo)</b> </font> I am trying to figure out if I need to replace the windshield wiper motor, is it just one motor or is there one for each wiper?  Because one of the wipers is working fine, the other over-extends itself or often does not move at all.  I also can't figure out how to get the panel off to get to the motor or I could have probably would have been able to answer my own question.  I have just recently started working on cars so I apologized if this is a ridiculously stupid question.  Thank you! :)

Answer
Its not stupid.  The wiper arm mechanism is most likely the culprit.  You need to remove the 2 wiper arms first.  Then there are 2 screws on each side of the panel and then another one right in the middle of the firewall.  Now remove the panel and access the motor and linkage.  Roger
