Power window service R1 1963

[Devildog]

Hi all, have not been on for a while. My 75 is running great. I am helping a novice owner with R1. The circuit breakers on the power windows often go intermittent. I reviewed some old threads and saw a copy 17FEB64 service letter suggesting moving breaker from firewall to inside the cockpit to avoid high heat.

I looked in service manual but it has nothing on wiring of window circuit.

1.Is there a circuit drawing for R1 power windows?

2.I saw comments about adding an additional spring to lift window

3.any articles available about servicing these old windows

4.maybe an update using newer relays, etc. rather than designing from scratch?

Thanks for all your good help
