Hi all, in particular Dave, I'm hoping that someone can post up some photos of the heater box mod gmh did to fix the cable bind I've heard of, my friend is playing around with his heater mechanisms atm & would a description of the mods done please, looking forward to the replies, Gary.
Hi Gary, I got some wire from a lawn mower shop, it was slightly thicker than genuine but still fitted the sheath. Made up a jig for bending the wire to look original and it works way better than expected.
I'll see if I can find the link to thread.

I'd be interested to know what GMH did to improve the situation and when in 73 this came into effect, after July when my car was made I assume.

I did Marty's upgrade to the heater control cable recently and it was a big improvement over my old kinked cable. If you do this modification make sure that the loop you make on the ends is off to the same side as the tab for screws, otherwise you'll have to try to twist it around later.

The mod is kind of what Marty did but not so severe. November 1973 was when the modified parts went into production and the dealers were asked to check the control functions of customers cars as they came in for service and perform the modifications, if required, at no cost to the customer regardless of whether in or out of warranty. This was because the heater demist function is the requirement of an ADR.

^^^ lol, I'd rather R & R an LC/LJ heater box than perform any major repair works in the engine bay of most late model compact front wheel drives.
