Can a complaint be filed with Heath Department Michigan if it is un safe to not have air conditioning in sleeper of a tractor trailer?

You can always try, but it's probably going to be to no avail. Nowhere in the FMCSR or FMVSS does it state any requirement for air conditioning to be available or serviceable in any sort of commercial vehicle.

If your boss man wants to put an idle shutdown timer on your truck, and not have an APU or other means of providing you with climate control when that truck is shut down, they can very well do it.

Have you considered driving for a different company?
