Now, that it's again hot, she finally wants it fixed. The regulator on this model was quite small, about 1.5 x 1 inch, and apparently fried itself as it could not dissipate the heat it generated. MBZ has discontinued it and makes you replace it with an entirely new motor and regulator assembly for well over $200.

Question: Has anyone worked around this problem with an aftermarket regulator and perhaps a heatsink so the original blower could be still used? I see Chinese regulators that appear to be modifiable for under $40 but can't tell their actual size to know if they will fit.
