I've owned five Toyota's over the years. At the moment have a 87 Corolla, 03 Cam and a 98 Cam.
Mostly I have reached the blower fan in the dash area by compressing the sides of the glove box together to disengage the "ears," although on the 03, I also have to unscrew a rod of some sort.
But have been unable to figure out how to get at the 98. Any secrets. Squeezing the sides of the glove box does nothing....
