Hello

it's been a while since I looked around here, I hope people can help me

I have just build into my car a New electronic Air COnditioner system, I would like to make a custom A/C panel that will allow me to toggle between 3 modes with a single switch.

for now

Basically what I want to do is use a single momentary push button type switch to toggle between sending power to 3 relays

these will 3 relays will be

1. OFF
2. FAN MODE
3. COOLING INC. Fan mode

I would like it to have a memory for everytime the car is switched on the same setting will be avil.


I would also like to add a Vent output setting. Change fanmode/cooling per vent for when No passanger, and would like to also be memory ..


thanks guys
Shaun
