[DML] Re: A/C and cooling fan relays sticking

["David Teitelbaum" <jtrealty@xxxxxxxxxxx>]

I am not familiar with your fan relay but it sounds like the diodes
you used are too "leaky" allowing some currrent to leak through,
enough to hold the relay in but not enough to pull it in. Try doubling
up the diodes for a higher front-to back ratio. That is put another in
series with the one already there.
