The blower motor in my car (85 190E 2.3, 130K) squeals on colder days. I asked the tech to lube it during the 30,000 mile service at the dealer. The service advisor told me that it cannot be lubed - it has to be replaced if it goes south. Is that true? Is there no way to lube the blower motor on a 85 190E 2.3?

thanks.
