Question about 1994 BMW 3 Series
Hey jacob, there are a number of things that can be wrong, let's start w/ easy cheap ones...1st, the easiest one is low coolant. If the level is low, it won't circulate thru the heater core, so no heat. 2nd thermostat stuck open. If this happens, the engine won't reach peak operating temp, and again, no heat. Pretty easy to check, is your car running cold (or low normal range?) If the temp gauge shows it's warming up in 5 - 10 minutes of driving, and is in normal range, then it probably isn't the thermostat. 3rd dash control that you use to select heat setting is either vacuum controlled (no vacuum @ switch possibly) or thermostatically controlled (faulty control), both of these could result in no flow of coolant to heater core, 4th a plugged up heater core (rust and corrosion) preventing coolant from flowing thru heater core. Let me know how u make out.
