Anyone know what this is/does?
From my 1974 T/A 455 auto with PW, PDL, A/C and rear defog? Is this a relay for my Power Windows maybe? P.W. not working and I thought this might be the problem. Thx.

Hi-RAM
There are no part#s at all but these letters are on the bottom of the part near the 3 spade connectors: Hi - RAM. Dave

Blower motor?
For the rear defogger or the heater system?

Everything looks right for the power window relay, except the Orange wire should have a Black stripe.

Ames catalog
I looked at the Ames book and they do show Blower Relays that look similar to what I have but the ones they have are 4 or 5 terminals where mine only has 3 terminals. I do have an original 1974 Pontiac service manual and there wiring diagrams do not show the PW window circuits anywhere. I also have a Chilton book and nothing there either for Power Windows. Weird.

Or, if you have the 1974 Fisher Body Service Manual, it's in Section 10.

You are correct!
Section 15 does have the schematic for the power widows and more so many thanks HFR. Also, that is a PW relay according to the schematic, the question now is where can I find a replacement relay?? Dave
