SL500 blower motor

Hey all, I have a 2000 SL500 whose blower motor went out. The indie said the strap broke and let the motor rub on the housing and burn out. I gave him a new motor with squirrel cage etc but the fan works intermittently. He is convinced from his reading online that the regulator is the culprit, but said there are several different to choose from.
There are 2 different choices, I think i bought the Behr motor but he doesn't think the regulator comes separate. Any ideas which regulator to get?
Many thanks in advance

Your mechanic needs to do basic troubleshooting to determine if it is actually the regulator that is at fault. Otherwise you are just rolling dice. The regulator is a separate part from the blower. I don't see one available here or at FCP either. All I see available on eBay are used OEM ones or new Chinese ones. You might need to find a different mechanic. When my blower went out on my '98 it was due to a melted fuse, since they used a fuse block contact with minuscule contact surface area. There are several things that can cause a fan to be intermittent.
