1992 Deville Blower won't shut off

Looks like the fix is replacing blower control module & possibly the weak blower motor itself. For the life of me I can not find the module in this car.

Is it under the hood or is it behind the glove box. if I follow the wire from the motor it looks like it joins a harness that goes through the firewall to the glove box.. keeping in mind that I am not a mechanic but I think I can replace it myself to save some dough.

Or is it near the Blower Motor itself
Seems like every forum has it near the blower... above or next
This is a 92 deville

Dealer her in Florida wants $194 Used Parts $75.00
I can't find anyone..even the used parts guy that knows
where in the world this part actually is
Part is AC/delco 15-72530

Could someone give me a hint...much appreciated

Under the hood, look along the firewall under the relay/fuse holders. Its a bugger to get at and out becasue of the relay holders.

Thanks a bunch
I removed Maxi Fuse/relay tray and there it was.
Replaced with Junk yard part for $50 bucks and voila..
back in business
