concorde heater system

I have the usual problems with the heater controls on my 95 Concorde. I took
out the circuit board and resoldered everything and it worked great for
about 2 weeks. Now it goes on and off again when ever it feels like it. Can
I take the controls out of a different car/van either a newer or an older
one and will they work better than the 95 control set?
Thanks

There's some dude that repairs them and sell them for $50 on ebay,
guaranteed. I couldn't say how good he is generally, but I bought one and
it worked okay. If his guarantee was good that would probably be worth $50
was my thinking.
