Fix that blower switch

The fan switch is possibly the most over engineered for a pull/push switch that I have ever ran across, as they are not available I took the time to find out what makes them work, or not work in most cases and the results are the usual suspects, curd on the contacts.
Here is what you do. Turn the switch to off, all the way in. Use a small 1/8 inch screwdriver and pry the 4 small metal indentations level, try and not over do this part, as level is quit substantial. Take note that on the metal surface that there are two holes on the side with the single lucar connector for reassembly. After getting the metal pried out, lift very carefully and as straight up as possible, this will save you a lot time putting the guts back together. Clean the inside of the plastic and sand or wire brush the copper to a shine, the sides are the only parts that come into play. Now the small floating connectors on top of the plastic should be cleaned, but be very gentle and hold the sides where the springs are with your fingers, they tend to want to go booong. DO NOT PULL THE SWITCH ON DURING THIS OPERATION. If the springs are loose, you will need a small needle nose pliers to get them back in place.

Getting it back together is just a matter of using the right orientation, (remember the two holes), there may be a slight resistance when you go back together, make sure the small connectors on the plastic are in line with the plastic. Use long needle nose or screwdriver to tap the metal flanges back in place; the key word here is tap, no hammer. I used a small block of wood.

You are back in working order.

I found out a long time ago, that putting a relay on the heater switch, lengthened the life of the switch immeasurably.

I'll see what I can dig up for you, by the time I find it, I'm sure someone else will have helped out. As my time frame with work is probably not until Wednesday.
