BlowMyWhistle 0 Report post Posted January 31, 2013 Hi Y'all, I know I've asked this before, but I been doing some research on it and need a quick answer... The 3 slides for the vents, footwell, cabin and screen... Would I be correct in assuming the central slide (cabin) is fresh air only? Not heat? The problem is I have unremitting HOT coming from the top and bottom vents only, unless I close them. The central slide is fine, but the only one I can have open without a blast of hot air. My sources tell Me that it could be a) both the motor controls behind the stereo, or the mono valve. I can get a new valve easily enough, but they not free, about $130 from USA, more on Pelicans... Had this once in an e34 in NZ, was just a fuse! I think it unlikely for both motors to similtaneously fail? It'd be nice to be able to have ful air con, specially days when it's 40*C The ear con will only blow cold thru the central vent, top open = hot, bottom open = hot. Regardless of the temperature controls. So why only top and bottom, not centre slide?? Quote Share this post Link to post Share on other sites
BM WORLD 1258 Report post Posted January 31, 2013 most likely the heater valve unit in the engine bay is stuffed jammed up , perished seals etc. so the hot water just keeps on flowing through the heater cores. comon issue with these old e34 and e32 etc even in the e36 e39 e38 models Quote Share this post Link to post Share on other sites

Is that fresh air only, not thru the heater? Quote Share this post Link to post Share on other sites
