A/C engaged at all settings on rotating selector switch except air flow is only out of the defrosters. No panel or floor air flow, anyone else got this problem? Do I have a vacuum hose off or fuse blown or what ? Thanks

You might have lost the vac pump. Do the power brakes work ok? If not then check to see if the vac pump is still working. dave
You may have blown a fuse for your vacuum pump, or a vacuum line problemYour brake booster is powered by the power steering pump.
