    I discovered a couple days ago that both of the coolant hoses that fit beneath the intake manifold are leaking. Well, one of them is, but I'm replacing both just 'cause. Is there anything else that I should replace while I have the intake manifold off? (vacuum lines, for example) I don't want...

    Hello, I come to you all with a desperate plea. I have absolutely no clue what is wrong with my E46 right now. (2003 325xi) It has no heat in the cabin. I first tried to see if the ac worked, which it did. Then the heater core control valve, which was fine. Flushed the core, and it was...

    Now that the seasons are changing, my wife was observing that although she can get heat from under the dash and floorboards when she selects it, the dash vents only vent cold air when both vents are simultaneously selected. My question is this: Is the system working correctly or should heated...

    Puzzling question that I have been struggling with for a few months now. My 2004 330Ci is blowing warm air from the the air ducts regardless of the temperature selected on the climate control panel. This is mostly felt when the front vents are selected, a little less when either the defrost or...

    Howdy - I've just gotten my reliable 2002 325i working again and there are a few issues I need fixed stat. First is the blowers - when I turn on the vents, no matter how high or what temp I set the system to, I get no air flow. My previous mechanic had said it was either the blower motor or...

    I'm a new member, DIY'er and first-time poster. I have a 2004 325i sedan. Last week on a hot day, I heard a faint whine from what seemed like the blower. The sound was high, centered and deep in the dash, but a low-pitch whine, worse at higher blower speeds. I suspected bearings would be...

    I set my climate control to 23°C (England) and select auto. The heater starts blowing warm air and the air temperature in the cab raises to what feels like 23°C which is great. But.... After about 10/15mins all the heater vents start to blow cold. Including foot vents and the centre vent. If...

    I've noticed that my blower seems to not change the amount of air that comes out of the vent, no matter if it is on low or high settings. It's blowing cold and hot just fine, but the actual amount of air that is coming in does not seem to change. I can hear it get louder as I increase the high...

    Hey guys, I have a nice coolant leak that's playing hide and seek with me. I've narrowed it down from the mid to the top of the engine somewhere under the intake manifold. I'm thinking its the heater o rings, as the coolant puddles on the block. Is there anything else I could have missed? It...

    Hey there peeps, Long time reader, first time poster. I've been having an intermittent problem with my blower motor, one day out of the blue the climate control panel went dead, no lights or response from any buttons, then a day later it came back to life. Didn't see anything else odd for...

    Hi forum. So I know for a fact I have a stuck open thermostat. It never heats up passed the first dot unless its warm enough outside. I also had an issue with my heater control valve. It stopped working entirely. I read that if you just unplug it you have heat all the time. I did this and I...

    When I turn my steering wheel, I lose heat from the vents. Is that normal? I've never had that in a car before. I do have a bit of a leak from my PS pump, and a new HCV. Other than that, and the fact that a belt is attached to the A/c, I'm not sure what the correlation would be between the two.:hmm:

    Anyone using a block heater? Who are you using? Switching from a TDI to gas might be different but I'd like to think it can't hurt? My car has about 250k KM on it so I figure its time to start babying it. Remote start instead? Conflicted :woot:

    Hey, So I'm trying to fix the heater in my 325i. I have no control over airflow direction. I can hear the fan going, but (currently) it doesn't come out of any of the vents. I just finished a Final Stage Unit replacement, and there is no change. I'm going to be selling the car to a friend, and...

    I have an interesting problem. (not sure if this is relevant but I figure too much info is better than too little) I got into a rear end accident last november and have fixed everything (so i thought) but now that it is warming up again, I realized that the defroster and the floor heater are...

    Hello everyone, I want to start off with saying I'm not new to modifying cars, however, I'm having a pretty hard time stripping out everything I want behind the dash of my 2000 e46 sedan. I have seen this DIY for stripping down to the dash, and I have gotten more than this far...

    Problem : When the foot well is selected and the fan is on, heat is coming out. This does not matter what temperature you have selected. 59 or 91. The outside temp is 40-60 degrees. If you select defrost you will get outside temp air, if you select face/dash vents you will get outside temp...
