1980 300SD Servo bypass/Amp question

Took the upper cover off the ACC servo and it was full of corrosion, the thing obviously doesn't work and corroded in place. I want to install a manual bypass valve. My fan only work on high/defrost. I'm assuming my servo amp is fried. Getting a new amp should restore the lower fan speeds but since my servo is seized I think it would quickly burn out my amp. Will the fan run on lower speeds if I totally disconnect the servo and cap the vacuum lines?
