Relay for 74 deville ac blower help question...

[lentel]

Anyone know where to find this relay. I believe it is the auto relay for the ac blower. Its on my 74 deville
I found what the repair manual calls the lo relay but cant find this configuration
thanks for any help I am replacing the ambient sensor, thermal fuse and a couple other ac blower related items that are really crusty and look bad

Not the greatest photo but to me it looks like its just mostly dirty.   The terminals don't look especially corroded especially given its age.

I have used ones?

That is the Blower Fan Relay. There is probably a LO-AUTO Switch mounted ON the dash control unit, which is Not a relay.  I'm not very familiar with 71 & later, but there were still 2 or 3 hokey switches On the control unit back then. And they do go bad.

Mine was going bad .... intermittent operation. They are really simple and as long as the coil circuit is complete, you can pull those apart and repair/clean them. The relay works great now.
