2004 BMW 330Ci Q&A
2004 BMW 330Ci Question: I turn on the heater but cannot get any heat.
no heat is coming from the system.only cold air blowing when heater turned on. - repair cost
could be as simple as low coolant level. this system uses an electrically controller heater valve which may have failed. or it may have a problem in the controller. after trying the basics, you should find a good local BMW shop that can diagnose this. - overbys
