The heater blower switch in my car only works on two of the speeds. It works on low and medium but not high. I am looking for a new switch and it does not seem NPD sells them. I have found one made by Old Air Products from CJ Pony parts. It is fairly expensive so I wanted to know if anyone has used this switch or had good luck with any other switch out there.

Non-A/C? I'd try cleaning the switch first, should be able to bench test and make sure it's not something else like the resistor.
Make sure the switch bezel has a good ground. I know on a 65-66 with a 3 speed fan that the bezel mount to the dash is ground to complete the circuit. If the paint is real thick on the dash or screws not tight, this can cause issues with the fan.
Yes this is an non A/C car. I actually replaced the resistor with one I purchased from WCCC which was in really good shape. I will remove the switch and try cleaning it and see what happens.
Thank you, Corey
