Hello all. About a month or so ago, I saw my ac lights flash for around
25 or so seconds, then everything was fine, they never flashed again.
But just recently my fan has started giving me trouble. At first it
would start up slow, but as you drove for about 10 minutes it would
work it's way up to full speed. Now it is getting to the point that
full speed is quite slow, and sometimes it doesn't work at all. When it
doesn't work, it seems to help to turn the car off and back on, then
you get some fan, also if you push it to high, it is only blowing at
around half speed. I am pretty savvy with cars, and would suspect there
is some kind of resistor somewhere. But I don't know where to begin
with the ECC

Your blower motor is probably going bad. My blower motor resistor has
gone bad twice-each time no fan at all. You can replace the blower
motor.Have to remove the glove box and knee guard . The blower comes out
with three or four torx screws. The resistor is next to the blower on
the left and comes out with one screw. If you aren't ready to pull the
motor, You can spray some light lubricant into the outside intake under
the passenger side cowling beneath the wiper. Have to remove four screws
and lift the cowling up,may have to lift out air filter. You can then
touch the Squirrel cage and rotate it by hand. If you feel the
resistance of bad bearings, order a fan from FC Groton.
