hi
have to do mine tomorrow(98 mystique)its going to cost $20 canadian for the resistor pack from the dealer.
it was a little white 1x2 inch door in the passinger footwell up close to the top of firewall and just to the left of the blower motor.held in with one robertson screw.
mine had the recall done in 1999 so i had to buy it.
very easy replacement.
on mine the resistor block was mounted to the white door(access panel)
pack was grey and crumbled very easily.
hope this helps
regards,jeff
