Just FYI for anyone either wishing to clean their Hurricane (perhaps Aquahot) radiator/fan units or to replace the fans as I did. In my '99 Marquis I removed my front lower drawer which presents each screw to the fan unit except the farthest away (vertical side) which were also not visible. I had to purchase a small (4 inch long) ratchet screw driver with short screw driver bits (less than 1 inch) to work in that small space. While I had the fan cover off I hit the front unit with compressed air to attempt to clean the radiator portion.
For the desk in the living room, rather than being a difficult location to replace/clean the fan/radiator, it was pretty simple. There were 4 screws that connected my desk to its base. After removing those the desk separated with a little lift (two people is a better idea but I was alone). It appeared that my fan had been replaced in the past and the unit was labeled "Radio Shack" and rather than a .95 amp rating was only .32 amp which partially explains why my air flow from that register was so weak. Having removed the desktop, I had easy access to clean this radiator too, and there was a thick film of dust on the fins (which I hope I removed from the unit upfront that I couldn't see).
This desk radiator fan also was held in by 3 (missing one screw) screws with nuts, rather than the plastic push pins that the other three fans I've seen so far. So, looks like an aftermarket "fix" gone very BADLY. I did go ahead and use the screw/nut to attach the new fan.
For those having no slideout in the rear bedroom like me, the bedroom fan/radiator was accessible by pulling the two draws then unscrewing 2 cover panels. I've cleaned this one with vacuum and compressed air, but there is so far not enough room to removing those pesky vertical face (of the fan cover) screws - 3 of them. This vertical surface is up against the wall to the engine compartment with less than 1 inch clearance. I have still not removed this fan unit because I ran out of time in figuring out how to get to those screws.
The last obstacle then is the bathroom fan beneath the sink cabinet. I looked at it quickly but didn't go further. Nothing obvious as to how to access it but when I go back I'll see if the carpet in the lower shelf comes out. It may cover an access panel. I'd hate to think that they simply installed the fan/radiator, then moved the cabinet on to that. I can only imagine, given the amount of dirt I saw in the front desk unit, that this unit is also very dirty. Perhaps the only thing I can do is to blow compressed air into it while vacuuming through the inlet air vent to the right of the cabinet.
I had already replaced the refrigerator unit fan/radiator. That unit was easy to get to by simply pulling the left had draw under the fridge. There was plenty of space to get to all the screws.
I hope this helps another who is wanting to clean these units. I recommend you do so. Other than the weak replacement fan (.32amps) that was obviously replaced in the past (why would Beaver use a Radio Shack fan when the rest were Mechatronic), all other fans have been the same amp rating .95 as my new fans but the new fans do allow more air to be pushed.
