Volvo Repair: 91 Volvo 940 Turbo Wagon AC issue and Central Lock issue, vacuum servo, volvo 940

Question
The AC blower in my car seems to be cut in half under acceleration, any ideas.  

Also the drivers door will not lock even by hand, it's like there is something jammed under the lock.  All other doors lock including the hatch.  Any suggestions on that one too.

Thanks,

JT

Answer
Jason, These cars  are prone to this stuff.  Its the recirc vacuum servo that is usually the culprit.  Real fun to replace that thing too.  As far as the lock, I would pull the panel off and see if there is anything bent or stuck.  If you are not comfortable doing that, have a Volvo shop check it out.  Roger
