Seat heater repair success?

It worked for me.
I repaired my seat heater at the beginning of the winter and it's been
working ever since. Granted I only use the car on weekends, but it's every
weekend. I was leery of the fix but I took the seat apart, found the break,
twisted the wires together and soldered them together.  I was surprised at
how well the solder flowed after reading some of the reports of difficulty.
The repair never got hotter than the rest of the seat and seems to be
fine.  Maybe it was the solder I used but I don't remember it being
anything special, just electronic type.  I made sure the iron tip was well
tinned and clean and that was about it.
