FAQ > Door Glass and Side Window Questions
The   drivers   side   power   window   door   glass   in   my   Lincoln   Town   car   has   stopped   working   in   the   middle   of   it's operation   and   won't   work   any   more.         I   can   hear   the   motor   operate,   but   it   doesn't   do   anything,   Can   Phoenix   Glass repair this for me? We   sure   can!   In   most   cases   in   vehicles   like   yours,   it   usually   requires   replacing   the   entire   power   window   regulator   unit   that   raises   your window   up   and   down.      Over   the   years   we   have   found   that   this   is   a   common   problem   on   many   vehicles   that   use   this   type   of   design.     Unfortunately   the   unit   itself   is   what   is   referred   to   these   days   as   a   "non   serviceable   item"   and   cannot   be   repaired,   your   only   option   is   to have   it   replaced.      For   information   on   having   us   do   the   repair   work   for   you   just   click   this   link   and   it   will   take   you   to   our   Door   glass   power window regulator repair and replacement   page.
What about replacing it with a used power window door glass regulator assembly? We   will   be   happy   to   do   that   for   you   but   from   experience   we   recommend   you   replace   the   window   regulator   with   a   new   “OEM”   or   after market   “OEE”   window   regulator.      A   used   assembly   sounds   like   a   good   idea   but   in   the   reality   of   this   situation   it   absolutely   isn't.      Keep   in mind   that   a   door   glass   window   regulator   of   this   type   must   endure   a   significant   load.   Buying   a   used   part   that   is   at   or   about   the same   age   as   the   broken   one   your   replacing   isn't   a   good   idea.      Most   regulator   assemblies   must   be   contorted   or manipulated   to   remove   and   replace   the   units   within   the   vehicle   door   which   places   stress   on   the   older   as   well   as   brittle plastic   parts.      Many   times   even   when   it   appears   all   is   well   the   plastic   parts   will   have   small   fractures   you   may   not   see at   the   time   but   after   the   first   few   times   of   operation   one   or   more   of   the   parts   will   fail   and   you   will   be   right   back   here buying   a   new   one   in   a   very   short   time   frame.      One   major   thing   to   consider   is   that   when   these   parts   fail   it's   very possible   that   the   door   glass   could   fall   to   the   bottom   the   door   and   be   broken   leading   to   an   even   more   expensive repair.      These   types   of   window   regulators   work   well   as   long   as   they   aren't   subjected   to   any   additional   loads.      If   you take care of them they will do their job for a very long time.
Things you can do to help prolong the life of your window regulators. 1 . Operate   the   window   at   least   once   a   week.      This   will   help   the   windows   keep   from   becoming   stuck   in   the   glass   run   channels   they operate in as well as lubricate the regulator mechanism and electric motor bushings. 2 . "Never"   operate   your   windows   especially   an   automatic   power   window   in   frozen   icy   conditions   as   they   can   be   literally frozen   to   the   Glass   Run   Channels.   Operating   the   window   in   that   situation   can   and   will   cause   major   stress   on   the   frozen plastic parts possibly causing them to shatter or pull apart. 3 . Keep   the   window   felts   that   the   glass   travels   up   and   down   in   clean,   lubricated   and protected   with   a   product   such   as   "STP's   Son   of   a   Gun"   on   the   rubber window   felt   glass   run   channels.      Some   people   even   use   products   like   WD- 40.      Be   careful   what   you   use   as   some   of   these   products   can   attack   the very item your trying to protect so read the product labels carefully.
I had a power window door glass replaced in my Cadillac at another auto glass store a few months ago and it hasn't worked properly ever since, can Phoenix Glass fix the problem? If   the   problem   is   glass   related   we   sure   can.      A   Cadillac,   like   many   of   today’s   vehicles,   is   a   fairly   complicated   automobile.      We   would   be more than happy to have one of our Phoenix Glass technicians look at your door glass and make an assessment. Our   first   thought   is   that   the   auto   glass   technician   that   originally   installed   your   new   power   window   door   glass   more   than   likely   wasn't aware that the power door glass window in your Cadillac must be calibrated during the installation.
I   have   a   Chrysler   PT   Cruiser   and   my   door   glass   window   regulator   needed   to   be   replaced.      I   purchased   a   new   one from my local dealer and it’s a totally different design from my original one, what’s up with that? We   came   across   the   same   situation   and   we   were   also   told   the   same   thing   by   our   local   dealer   here   in   Knoxville, Tennessee.      Believe   it   or   not   the   plastic   regulator   on   the   left   in   the   photo   is   the   factory   replacement   for   the "OEM   Factory   Installed   steel   regulator   unit.      At   first   glance   you   can   see   that   it   works   in   a   totally   different manner   and   doesn't   look   near   as   durable.      It   has   a   couple   of   serious   issues,   one   is   that   the   wire   that   goes   to the   motor   moves   up   and   down   with   the   window   so   great   care   has   to   be   taken   to   ensure   it   can’t   get   hooked   on anything   within   the   door   as   it   runs   through   it’s   course   of   operation.      The   2nd   is   that,   at   least   in   some particular   year   models,   the   silver   metal   support   brace   in   the   photo   cannot   be   used   which   takes   away   quite   a bit of support from the inner layer of the door.

In   an   effort   to   save   weight   many   auto   manufacturers   began   using   various   designs   of   this   type   of door   glass   regulators.      Ford   by   far   isn't   the   only   manufacturer   that   uses   this   type   of   door   glass window   regulator   as   they   are   commonly   found   in   everything   from   Chevrolet   to   Nissan’s.      One   of the   main   problems   we   see   happening   is   that   the   plastic   parts   carry   the   entire   weight   of   the   door glass   and   become   aged   and   deteriorate   to   the   point   that   they   fatigue   and   release   the   cable.   The second   most   common   problem   is   that   the   plastic   that   retains   the   lead   anchor   attached   to   the   end of   the   cable   fatigues   and   detaches   from   the   cable.      When   that   happens   the   cables   become tangled   and   damaged   beyond   repair   in   the   drum/pulley   mechanism   that   the   motor   or   window crank turns to raise and lower the door glass window.
