Raz, my pal just had similar issues

I "BELIEVE" his is a 2000

The relay was (I think) Passenger side, under the headlight--and under a "Pain in the Butt to remove plastic cover"

With the battery removed he said you could sorta "peek" at it

He told me the EZist thing for them (him and another feller) to do was they removed the headlight. With a pencil type soldering iron they sorta "MELTED-CUT" a "Square" out of the Pain in the Butt Cover, directly above the relay. Said it was EZ then! They replaced the relay. Then they silicon-ed the plastic square back in. He said fixin' the cover was really unnecessary, as it really served no purpose, other than as a cover, but they did it anyway.

. Or you can take it all apart to get to it!

I got you a diagram--see left side

Let us know how it goes

No diagram available from "Mitchell I"

In a chart they did say the blower motor relay is located behind the glove box on the HVAC housing

Sorry 'bout the screw-up above

Keep us informed
