this is what happened. the slide would only deploy 1/2 way. I stopped by a large nearby RV dealer and asked if they worked on PowerGear slideout mechanisms, and could they work on an Airstream. They APPEARED knowlegable, and said they worked on power gear systems.
What a mess. 200 dollar later and 20 miles down the road after I parked at home, the slide was out 1.5 in on bottom. Went to a rally, only one lock would retract, next morning both retracted but slideout would not deploy, it would not move.
Brought it to Airstream dealer............1000.00 dollars later
he opened up the access panel under the slide and bolts and nuts FELL OUT. the microswitches on the locks were all loose.
I guess the lesson here is to ONLY GO TO AIRSTREAM DEALER....
hopefully I'll have no further issues!
