Imagine my surprise doing a little googling and finding my recently purchased 1991 Volvo wagon on the internet. Thanks Randy, my wife loves this car and it is now her daily driver. I opened up the rear life gate and adjusted the rod from the outer lock release handle to the latch mechanism. It was locking properly with the doors, but would not unlock, due to the rod being short. A couple of 360 degree turns and problem solved. I must say I was thrilled to find a car such as this that had been given major TLC maintenance over the years. I think it was a steal at $900, looking forward to many years out of this car.
Thanks again, Alan
PS - I liked this car so much, recently bought another, a 1995 850 turbo wagon. Not in as good a shape visually as this 91, or as well maintained, but lots of potential nonetheless.
