The hvac fan motor is in the engine bay behind the false firewall on the driver's side. First of all I would suggest trying to lube the exposed motor shaft bushing on the driver's side of the motor. That exposed bushing gets dirt in it, runs dry, and eventually either lets the shaft scream or starts to seize up, causing the motor to get hot, thus the smells. That exposed bushing is the biggest problem with this el cheapo Bosch motor. It must be lubed with 3 in 1 oil or engine oil now and then. I do it whenever I lube the hood and door hinges. That might save it for quite a while.
But yes, to answer your question, that motor has been replaced in quite a few 164s. Use the identical motor from the Saab 9000 for half the price, about $60 or so.

One note: when I replaced the motor in my 91S with the Saab motor, for some reason the plug wiring polarity was reversed, and took a while to figure that out.
Almost all remove the entire fan/motor housing to replace the motor, while I have seen where someone used a Dremel to cut open the black plastic housing to lift out the fan/motor assy, gluing the housing back together again with silicone. Having removed the assy either way, you then have to change the fan itself to the new motor. This requires being careful, as it can be broken.
I think Steve shows a fan/motor replacement procedure in his "tips". Otherwise, take a look at the Fiat parts eper
