Rear defroster problems


Guest Anonymous

Recommended Posts

Guest Anonymous

I live in a cold area and my rear defroster is not working this winter on my '76 2002. I've looked through both of my repair manuals and can't find a thing about it. I was wondering if anyone could give me any insight on where to start checking for problems as the only way I can get my window to defrost is to keep my window open, and that's not fun in 10 degree weather. Thanks in advance.

It doesn't take much to break the flow of electricity through those thin painted on elements. JC Whitney has a repair kit for this for around $10. It's tedious, (picture: painting a house with nail polish upside down), but works well if you follow the simple instructions. Check all of the notorious points first: fuse box, clean all electrical contacts with emery paper, etc.

Get into a warm area check for open grid lines on the window it`s self. If there are any open areas on the grid find some conductive material to close the open circuit. With power off! Use ohmmeter to determine if there is continuity between both male spades of the rear def window. If there is continuity, check switch, and all grounds. There is one ground that is on the right rear bulkhead off the right rear male plug. FYI.

How does one turn on the rear defrost? My 72's dash is

faded on all the instrument labeling - it's been trial and error.

The rear defrost is the last function I haven't figured out how

to turn on.

switch is the fourth heater lever, then the defroster knob is the lower left side one on the instrument binnacle. They switched from 3 to 4 lever heater controls sometime in 1972, I think.

Sometimes one or a few grid lines don't work because they were scratched. Repair those breaks with the paint on stuff the other folks mentioned. It's also common for most or all of the lines to be deteriorated to nothing by age, sun, and overuse. In that case, the only repair is a new piece of glass. Email me for testing instructions.

    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
