Heat issue: check the heater valve, located on the firewall on the passenger side (LHD cars). There is a plunger on a steel rod. Push it all the way up and zip tie it in place. See if you have heat. If so, verify the vacuum source is good. If it is, the heater valve needs to be replaced, or left tied up. (I'd rather replace it)
