djbaba Posted July 13, 2012 Author Share Posted July 13, 2012 yup a guessed tht when a took the cover off on monday wish i didnt now but i have no idea what it is Quote Link to comment Share on other sites More sharing options...
Lenny Posted July 13, 2012 Share Posted July 13, 2012 looks like someone fitted some sort of power boost electronic box to the car at some stage to trick the sensors in to thinking it was colder than it actually is, this gives the car more power and may have come with a T piece like the drake box's you can buy on eBay so the fitting would have filtered the connection that they have fitted, i reckon if you remove the connector and hard wire them back togeather you should be as good as standard again mate.

djbaba Posted July 13, 2012 Author Share Posted July 13, 2012 thanks lenny so tht could be why its giving me a dtc U0100 hmmm if i solder them and tape them up it should all be ok as a was getting very worryed tht something was really wrong with the car nd as soon as i took the cover off a knew it wasnt meant to be there. thanks lenny :D:D:D Quote Link to comment Share on other sites More sharing options...

Lenny Posted July 13, 2012 Share Posted July 13, 2012 thank you lenny a think you might have solved it thank you no problem sir i would trace that additional red cable that leeds out of the fuse box and see wher it is going before i would include it on the new connection though because it doesnt run inside the factory loom of cables i would trace it to see if it is required.

djbaba Posted July 13, 2012 Author Share Posted July 13, 2012 lenny av had a thought would it be ok to remover the /disconect from the fuse box to have a good look at it or is there more to it Quote Link to comment Share on other sites More sharing options...
Lenny Posted July 14, 2012 Share Posted July 14, 2012 lenny av had a thought would it be ok to remover the /disconect from the fuse box to have a good look at it or is there more to it yes mate, ive unplugged the connector to the centre of the engine bay fuse box when fitting the drls because i removed the battery box to fit the moduiles to the rear of it. but make sure you have your stereo code before you unplug it, and disconnect the live feed from the battery before you unplug it too. its easy to remove jus lift up the blue flap to release the catch and unplug it, Quote Link to comment Share on other sites More sharing options...
djbaba Posted July 14, 2012 Author Share Posted July 14, 2012 hi i have had a look the day and the wire goes to a senor a think but it was tucked bhind the radiator and under the air box so am very confused now and it is also connected to the fan wires :P Quote Link to comment Share on other sites More sharing options...

Stoney871 Posted July 14, 2012 Share Posted July 14, 2012 That sounds like a bypass to the fan thermostat. Probably the original one has broken and this is a workaround. You may also find that there is an adjustment screw on the box in order to set the temperature at which the fan will cut in. Quote Link to comment Share on other sites More sharing options...
djbaba Posted July 14, 2012 Author Share Posted July 14, 2012 hi this is the part no 94BG-14N089-E1B am not sure if its a sensor or relay, couldnt find any screw or anything to set temps Quote Link to comment Share on other sites More sharing options...
djbaba Posted July 14, 2012 Author Share Posted July 14, 2012 that what it looks like http://www.ebay.co.uk/itm/FORD-ESCORT-MONDEO-FIESTA-RELAY-94BG14N089EA-/320734730018?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item4aad479722 Quote Link to comment Share on other sites More sharing options...
Lenny Posted July 14, 2012 Share Posted July 14, 2012 that what it looks like http://www.ebay.co.u...=item4aad479722 ive searched the part number and the result came up with this list of relays and their purpose, apparently this one was for drls but its not being used for that in your motor, http://www.fordpartsgiant.com/partlist/wiring-system-passenger-compartment-page-c~1997-ford-contour-1898334-1899250-1912786.html im now going to get the haynes manual and see if i can trace what the green cable is that is being routed to the yellow relay, we will get to the bottom of this lol im now thinking ford relays are expensive as in £20 - £30 per relay, so perhaps the fan relay blew in your ford perhaps due to water getting in to the fuse compartment, then the cheap option would have been to get a relay from the breakers, but the relay didnt match the fuse box, so we will bypass the socket and make it fit. im not sure but it seems like an explaination, im going to check the haynes as see what that red and green cable is from Quote Link to comment Share on other sites More sharing options...

Lenny Posted July 14, 2012 Share Posted July 14, 2012 hi lenny tht will be brill thank you. If u want the mora al strip it all back and take some more photos if tht will help any Hi mate, sorry to say ive had a look at the fuse board diagrams in the rear of the haynes manula and it doesnt show a list of the cables in the engine fuse board plug or what each one leeds to/from, ive compared the fuse box to the diagram though and all of your fuses and relays are present in the board, so i reckon if it had been bypassed then the original one would have been removed but this is not the case, all of your relays and fuses are in place.
