RE: [Chrysler300] Repair or replacement of vacuum switch



Grady Research (John Grady <jkg@xxxxxxxxxxxxxxxxx>) did an overhaul/upgrade on my ’64 heater A/C control switch by replacing the deteriorated & sticky internal sliding plates that route the vacuum to the various doors.  You might want to do this reasonably-priced upgrade while you have it all apart.  No nipples needed replacing but I believe he does that, also.  The plastic nipples have a little bigger OD than 1/8” tubing.  Whilst searching for tubing to make a probe for testing the doors, I found a plastic ink tube from a ball-point pen was just about right.


I now have a spare non-A/C switch core for a ’64 Sport with all the nipples broken off if you or anyone needs that.  Internal condition unknown.  I also have blue and black instrument panels for ’63-’64 and various and sundry gauges, switches and 120 MPG speedo’s (small s) for same.

  OK, after 25 years of faultless service, my vacuum switch for the heater and vents on my 64 300-K has had half the nipples broken off by a mechanic.  I need to either replace the switch or have this one repaired.  My memory says there used to be a member that repaired them using brass to replace the plastic nipples.  I have looked in the backs of Brute Force and Chrysler Club News with no success.  I have also placed a call to J C Auto, and am awaiting a call back.  

 The part number (this is for a non-air conditioned car) is 2290 089.  This number appears on the switch and in the parts book as well.  Any ideas of leads would be appreciated.  Maybe I will think of a few more on my own after I cool down more.

Thank you,
