1999 park ave. super charge. Driver and passenger FRONT only opens from inside, the outside handle will lift up when you pull it but will not open doors. Please advise.
Driver REAR working ok. Passenger REAR will not open inside or out. SCARED TO LOOK THE VEHICLE. Down to one way to get into the car. Can someone help ?
Thanks in advance for any help.

Are the doors unlocked when you attempt to open them from the outside?

yes they are

Linkage for the handles probably broke the plastic connectors. Did these all fail at different times?

This doesn't ever happen all at once. I'd guess they've been failing one by one over a long period of time. It you have the ability, it'* time to take off interior panels and get to diagnosing. If not, it'* time to take it to someone that can help. No fix can be performed for this type of issue without taking off the interior panels and looking around.
