E60 weak heat. No heat on passenger side.
This is my second e60 and the heat is just horrible. Driver side gets kinda warm and passenger side is cool. I-drive in the winter settings. Any suggestions? Antifreeze full. No check engine light. Car warms up normal. I don't get it.

Water valve fail in the open position to allow water to flow to the heater core for safety reasons. I have seen a few clogged heater cores. You need to check the temperature of the hoses going and coming from the heater core with a IR temp gun.

Is your outside temperature gauge reading properly? That external sensor is used by the cpu to set the load and achieve proper inside temperature.
