Central AZ car, in summer. NAPA-certified shop cannot locate the correct "FCM" aka 'radiator fan relay', and I cannot find an exact replacement online despite 3 days of searches. The closest I have found (image attached - black in color only) is part Part RY375 at http://www.smpcorp.com/web_app/catalog/publiccatalog.asp, ("RELAY - HVAC BLOWER MOTOR" at rockauto.com) but it does NOT have the correct blade/prong alignment. Part via NAPA catalog is not the right one, either, and I find no pertinent lists on sites for Bosch or many other part supplier websites.
Ford entities contacted by my mechanic refused to give him the orig OEM part number, and would only tell him that what we need "has been discontinued".
Pictures of the fried, Imasen(tm) 5-blade part marked on exterior housing "DC12V10A" (followed by "6A 11") FCM/relay I need are attached. (Black plastic outter housing w/white lettering, blue plastic inner body, 5 blades shown in upshot.)
I have been unable to locate ANYthing w/the correct blade alignment (two rows, three prong on the bottom and two on the top, 1 in each left and right corners) at all, much less one that matches the other specs.
I really need an alternative to having a used/salvaged part installed, as AZ summer weather allows NO margin for error and the car quickly overheats w/o the radiator cooling fan being operational.
The fan motor is temporarily 'jump wired' now so that it runs constantly and one speed - which seems to be playing games w/the AC's ability to produce cool air after just 2 miles of operation. AC and related systems have already been checked out by my shop. We don't believe that any other part is failing so as to cause the initial problem (FCM failure) and fan is operational w/temporary 'jump wiring' - but just not w/OEM variable speeds due to no 'relay'/FCM being in line.
I would really appreciate any assistance you can offer in finding an appropriate replacement part, OEM number info, and/or likely sources for alternate part which will actually work and match the DC/Amp/blade/blade-alignment requirements.
NAPA shop has checked all other related parts and systems, including engine compartment fuse box, fan motor itself, etc. Since the fan DOES run while 'jump wired', and will NOT do so w/the fried part installed or any other supposedly alternate part installed, we do not suspect any problem w/the fan motor itself.
Your help in finding the part I need or a source for it would be greatly appreciated!
