I just replaced the front heater fan and rear heater core in my 86 GL.  I
would like to mention something I noticed that is not covered in the
excellent web sights detailing this procedure.  First thing when using a
knife to pop open the welds holding the box together make sure you use a
locking blade.  My knife folded up on my index finger and cut from the nail
to the first knuckle on my index finger.  OUCH!!!
       The best thing is, now I have heat.  Of course it was 60 degrees
today.  Oh well.
I read that this is supposed to be a bad job.  It was time consuming but no
worse than changing a brake booster out in a GMC or Mitsubishi cab over.  I
do about one of these a week.
       Ken Wilfor@vanagain supplied parts and service was great,  only thing
Ken needs to send 11 clips, instead of 10.  Just thought I would share the
wonderful news with everybody.
