on my sd im trying to isolate each door actuator to find possible vacume leak as door locks are not working.on the 116 pulling carpet doesnt easily reveal splitters as on 123.im thinking i have to open each door and test each pod.any suggestions.car shuts off well.ive plugged green line to hvac,no change,dont think its tank in trunk.also trunk wont open when door key is turned.in the past ive found door pod to be a problem in the 123.lots of work to open each door,would rather isolate under carpet,but cant seem to get to it.

If the 80 SD is like the 81 SD, you must pull the carpet in front of the right front passsenger seat and test the lines there. You should be able to find out which line or actuator is leaking. If they are not leaking, you should be able to use the mityvac to pump them up and lock the locks. There are a multitude of posts on how to do it.

yes,your right ,id been looking at drivers side,thanks
