Question Manual Switch Between AC and Heat.

Hi,
I have an old electric AC unit, forced central air. A few years back a friend looked at it and seen a short in the wires after taking the front panel off the heating unit.

Every year since, I need to manually go and tie 2 wires together to switch from AC and Heat vice versa. There are 3 wires used, 2 Blue and 1 white.

When I went to change over to AC I untied the 2 blues and now forget what other 2 wires to tie for AC. I tried every combo with no luck. When I turn on AC, the compressor goes on but the fan blower never kicks in with every combo of wires.

Any ideas which wires need to be tied to make Fan kick in with Compressor.

Welcome to the forums

I'm not an HVAC guy but this doesn't sound like a good idea, I think I'd have a pro come out and take a look at your situation.
