Hi Rick:

 

Please check the separate 30amp foil fuse in the external holder up near 

your brake vacuum booster first.  It's bolted just to the inside of the 

engine firewall.

business trip.  When I took the car for a much needed jaunt up the
interstate I noticed that the AC didn't seem to work.  When I returned home
I checked to see if the compressor was turning,,,and it was, but the fan
(blower) was not blowing air...in any mode. i.e. fast, slow or automatic.
It is not a blown fuse because the blower motor is on the same circuit as
other things that work properly.  When I select 'economy' the compressor
turns off, so the climate control seems to work properly.  I assume it is
either the blower resistor pack or the blower motor itself.

as default?  Does anyone have the wiring diagrams and a troubleshooting
procedure?  I think I should check the blower motor and/or the resistor pack
with an outside +12 source to see if they operate but I don't know where it
is or how to get to it.

blower motor and resistor pack and checking them.
