Fan Not Working in Texas Heat, Need CCRM!

[DeepPower]

Car overheated in the sweltering Texas heat today, cooling fan isn't working. I've got to fix it fast. My first suspect is the CCRM, which I had replaced in April 2014 with an aftermarket I can't remember.

Anyone know the Ford part number for the Constant Control Relay Module (CCRM) for a 1989 SHO? I've found numbers like
E9DF-12B577-AB M
E9DF-12B577-DB
E9DF-12B577-AA M CORRECT p/n

but I don't know which one is correct. And a respected quality aftermarket supplier of such would be welcome.
SHOSource has them used, but I need something I can buy this weekend, to get me to work on Monday.

Thanks!

Edit: found correct p/n

I think they have various part #'s depending on year and whatever, but any with an "M" code from '89-'93 SHO should be what you need for an '89. Will have a big M on it Like this:

Don't really know anything about the aftermarket for these. I do have a couple good oem used ones for sale though, but wouldn't be able to get there by Monday.

Maybe Scott (sdpatt) or Texan Tony or another one of our comrades in that area will have something to offer? I'd PM them directly.

You need something close by try the lonestar sub section http://www.shoforum.com/index.php?forums/lsshoc-lone-star-sho-club.20/

Thanks for the replies.

I have an Advance Auto, AutoZone, and O'Reilly's within two miles of where I live, close enough for me to do a fast drive to pickup parts.
Now that I've calmed down a bit (having your SHO overheat in 100°F weather is frightening), I found my original thread on this here:
http://www.shoforum.com/index.php?threads/fan-not-working-can-i-hardwire-it.127492/
So I have a Four Seasons 37510 CCRM. My original module (found it!) was a E9DF-12B577-AA M and I've modified my OP.

My fan is a Compressor Works 733700.
I'm going to test to see if it's the fan or the CCRM. If it's the CCRM, if I can't get a replacement this weekend then I'll hardwire the fan to a switch for the time being. This is also a good time for me to install the police grill I recently bought.

Probably. The heavy guage wire that feeds 12 volts to the fan comes from pins 3 and 4 of the CCRM which are then combined into one wire, a brown with orange stripe. The feed TO the CCRM (sometimes referred to as the Integrated Control Module) is through pins 6,7 and 12, on black with orange stripe wire. Those three wires are spliced to a single black with orange stripe wire, which is then spliced to an 18 ga. fusible link, who's other end is connected to plus 12 volts at the ALWAYS HOT side of the starter solenoid on the driver's fender well.

If you don't have power to the fans, start checking backwards from the fan to the starter solenoid.

With the engine running and AC on full:
At the fan
Pins 3 and 4

With engine off:
At pins 6, 7 and 12 of CCRM
At the CCRM side of the brown fusible link
At the Solenoid side of the fusible link.

Thanks, that's very helpful. I have the schematic but I do not have the pin numbers.
For other member's reference I have posted the engine electrical schematic here:

I may have to wait until tomorrow when it's cooler, it's 105 degrees in my garage (even with all garage doors open) in this Texas heat.

Edit: Just checked, it, yeah, it's the CCRM. I checked the voltage at the connector. I was in the garage for five minutes and it's like a just came out of the shower... RCM claims to have brand new Ford CCRM modules, I emailed them to see if they are really in stock.

Thanks. Would you be able to get it to me by Tuesday the 18th?

I have run an engine fan directly off the battery in an emergency situation like yours.
Unplug your engine fan connector, get the correct push-on terminals and crimp wires onto them.
Run one wire into the car cabin through the back of the hood and through the drivers door window into the drivers area.
Take an electrical switch for a house and hook it into the circuit (and tape it up well).
Continue the wire back through the window , under the hood, into the battery area where you put an inline fuse at the positive terminal. Figure out which wire goes on the positive terminal in advance to see which placement runs the fan in the right direction to cool.

Use heavy gauge wire (take a look at your factory wire connector and get that size) and a 30 amp fuse, and everything is usually available at Walmart on a Sunday.

It is not pretty, but it will get you to work until your part comes in. And you have to remember to turn it off after a use, and turn it on by watching the temp gauge.

At this point, obviously not. I didn't know you replied until now. If you still need one PM me.
