I have a 94 acclaim and the back doors will not open. Yes, they are unlocked(manual locks). I have the door panel off, fiddled with the mechinism and soaked it in wd40 all night. I pried at it with a hammer while trying to open, kicked it, and swore and nothing still. The mechinism looks like it's working fine and I worked all the unlocking levers with a screwdriver directly on the mechinism but nothing. Any ideas?
