Bathroom fan, light, heater

The bathrooms in my house all have the same combination exhaust fan, light and heater. Each function has its own switch and the heater has a pilot light. The light and the fan work independently but when the heater is turned on the fan runs too. The switch for the fan on one unit went bad and needed to be replaced. The switches are small rocker type and look old. They consist of a combination single pole switch and 3-way switch that operate the light and the fan and a single pole switch and pilot light that operate the heater. I couldn't find anything like the old switches so I bought regular size switches of the same configureation. I'm am going crazy trying to figure out how to configure the wires so the fan runs when the heater is turned on without having the heater run when the fan is turned on.

Thank you for your wisdom oh great wizards of volt and amps,

Try this. Not sure if it's up to code, but it should work.

1. Hook up REGULAR switch to light and POWER.
2. Hook up COMMON of 3 WAY SWITCH to FAN.
One "runner" of the 3 WAY SWITCH to POWER.
Other "runner" of the 3 WAY SWITCH to PIGTAIL.
3. Hook up another REGULAR switch to a PIGTAIL and POWER.
4. Combine PIGTAIL from step 3 to PIGTAIL of 3 WAY SWITCH
and hook up to your heater.

Might have to flip the 3 way switch around to make it switch off or to the HEATER switch when down. Hope this helps. Let us know how it works.
