Asked by mothman Mar 23, 2013 at 06:47 PM about the 1989 Chevrolet Celebrity

Question type: Maintenance & Repair

On a 1989 6cylinder celebrity wagon does the regulator just pull out? I am trying to pry it out but it will not come out.

What happened? the vacuum source fell off? sucker tool revealed a leaker? These may be integral, that's why it won't pry, but the guts of it can be serviced. Think there's a diaprhagm and a plunger...that's about it.

you know jason, haven't had experience with them, just read today what they are and how they affect your automatic transmission...the vacuum builds up, till the vacuum modulator changes gears...that's about the jist of it. no modulator=no switchin' gears.

could be a hinge action, thought it was just a plunger, but all cars seem the same but different somehow....still can't figure on so many different steering wheels that do exactly the same thing...
