Re: [DMCForum] Climate control fan & hot relays

[Ryan Wright <ryanpwright@xxxxxxxxx>]

Thanks Michael & Chris. Yeah, sounds like my fan fail module is screwy
then, or was rewired at some point in time. I'll take Chris' advice
and build a quick link to replace that, and continue with my plans to
replace the other relays & circuit breakers.

One more question for you: Is there any reason to replace the "rpm
relay"? I see that John sells it in a kit with the other modules but
I'm not sure if I need it.
