Help. Rear fuse panel question
Thanks in advance. My car is a MY 92 C2 cab w/tip
I am having the AC/Heater blower woes. Rear blower and fuse work, so I ordered two new relays PN#141 951 253 B...
I will assume it's the green relay in my car (see photo). My big question is what is that plug for?

Next... The new relay doesn't look much like the old one (green one on left). I don't seem to have the right relays here... I'm just buttoning it back up the way it was until I get some help from you guys...

It sure as heck doesn't even come close to the one's I bought
Do you know what that part number is now that I've put it all back together again?
Thanks
All the blowers are erratic. Front ones cycle on and off. No heat/blowers at under about 75mph... Rear blower operates..

That plug plugs into a module for the rear window heater, which cabs don't have obviously. The module fits into the clear space just aft of the relays.
About the relay's...
Can you test the old unit ? Put 12vdc across the coil and measure continuity. If your new relay has the same coil voltage and resistance, amp rating for the contacts and pin out, I suppose that will work.

The rear blower relay is the same part as the two relays in the front fuse box for the ac, and oil cooler blower motors. You could swap them to see if it's your problem. No rear blower causes no front blowers when the temp **** is moved off the cold "blue dot" position.

It's a double relay 2 coils with separate contacts.

You can find 2 of the same relays in the front of your car (central relay and fuse box)
Before you buy a new one, try with one of these relays.
I think R04 is the same. This is the relay for the oil cooler.
