2000 bonneville blower issues
my 2000 bonneville SLE just started to make an incredibly loud vibrating noise from the HVAC blower when the blower speed is above the 3rd setting. below the 3rd setting it still makes noise, but not as loud. everything else (hot and cold) still works, it is just loud.
i suspect i have a bad bearing or something on the motor and was planning to replace the whole motor. could it be anything else?
is this a do it yourself job?? has anyone else had a similar problem and had success with repairing/replacing the blower motor themselves? if so, please post any tips you may have.
thanks in advance!
