Defroster cable
Posted by: Don63Vair2 ()

Need to replace drivers side defroster cable and had a couple questions.

1 - Is the end of the lever where the cable is attached supposed to be straight? It is currently tilted to the left (See attached photo)
2 - Is the replacement straightforward or are there any special adjustments to look out for?

Thanks

Every one of the ones that I have seen have been twisted like that.

Does it mean that they were straight when they left from the factory, not sure.

It was straight when new. The arms are pot metal thus a soft metal. When cables become difficult to move the ends twist and break.

Labor to replace the cable is only difficult because of under the dash access. Removing the front seat will gI've more room to work.

I use a motorcycle cable lube tool for keeping the cables from becoming sticky.

I do not often disagree with Steve, he has been at this game way longer than me, but I think they were tilted from the factory, to align them with the cable holders (clamps). See picture above.

Either way they came from the factory, DO NOT straighten them at this point!

I have never seen a straight one. I have fabricated some of those levers from thick sheetmetal to replace broken levers.winking smiley

Hi Frank: not a big deal here but I have a new in box def lever and it is indeed straight. Yes you are correct almost every one that got constant use ended up being bent. I always figured it was because the two cables were different lengths and the 'drag' was different due to that. I will agree NEVER sraighten the bent piece, the pot metal will be weakened even more. In fact if it is working leave it alone.

I used to make from 1/8" bar stock a top lever with a stud sticking through both sides to repair the local cars here that were broken and Clarks used to offer a kit to do the same. I do not know who was making their piece.

I have been repairing those levers since the '70s with the same method Frank used but I can assure you...they were straight originally!

The passenger side defroster cable is longer and more likely to get wet, corrode, and become harder to move than the driver side cable, the unequal resistance would bend the lever.

Sometimes one cable end would buckle and break off first, but the lever would still be straight. I would shorten the cable casing and I have a tool to re-curl the wire.

Thanks for the replies. I'm getting a replacement cable, the original is in real rough shape.

So do not try and straighten out the lever?

Right, do not straighten as it is already weak from being bent.

I never saw a new defroster lever or assembly. They bent real early in life around here then. ????
