e-21 heat question

Recommended Posts

Bill,

It may be that the cable has come unattached or the plastic that the cable attaches to has broken. He can look at the heater valve, under the hood, and see if the cable is still attached there. Move it manually, to the desired temperature, if he doesn't want to begin rooting around inside of a cold, plastic dash.

I have found that all of that fine stuff has a way of cracking and breaking on even a warm day. It's a bit simpler and more open on a non-A/C car, too, otherwise it's really crowded in there.

Bill,

Jess's, downtown location, is already open! they serve breakfast, too. it's really not too early for a 'dog though.

let me know what you find. the heat knob is on a North/South axis and moves the cable, attached to the rear, on an East/West axis. mostly plastic with a bit of metal. there just ain't no room. heat temperature cable runs through a rubber grommet type of thingy in the firewall. cable has a fixed cover and the internal wire does the moving.

i was just back up in MD, for about an hour, on this past Saturday, to pick up another car.....a Sahara 73 2002a that i bought from Cuttie a month or two ago.

that protrudes through the dash.

If I remember correctly from rebuilding my E21's dash when I got the a/c back in operation a couple of years ago, the shafts are "D" shaped, and there are little spring clips that press into the shaft tunnel in the knob to retain the knob on the shaft. If the clips have come out or the knob is cracked internally, the knob won't turn the shaft and move the cable.

The knobs should be a pretty tight fit - if they pull off very easily, there's probably something wrong.

This is exactly what happened to a couple of the switches in my 320is. You can either get new ones, or if you're in a pickle and need heat ASAP, just pull the switches off and turn them with your fingers/pliers.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
