Front Blower--FIXED
#22
#24
Would you be so kind as to share a link to where you are buying the OEM relays? My 2012 RR HSE SC front blower is acting crazy (was running with the car OFF today, requiring me to disconnect the battery) and I'm going to try and swap with the back relay (which is working) to see if it fixes the issue. If so will need to order a new one. Have tried ten different searches and cannot find to save my life. I also ordered a new resistor. Any insight appreciated.

Ford Dealer
Re sourcing a factory relay, I presume that you do not have a Land Rover dealer nearby and would like one kind of immediately as opposed to ordering from BP Utah or perhaps Atlantic British.
In that case I would suggest you remove the relay and take it to the parts department of a local Ford dealer. Suggest to them that an older Lincoln Navigator or Ford Expedition might have a similar heater fan relay.
Our 3's parts, (improved), can be found on newer, (circa 2010), Ford full sized trucks and Explorers as our 3 was a test mule for future Ford production and it took about five years for our 3's systems to be reliable enough such that Ford would use them on volume production vehicles.
I say go to a dealer as opposed to picking something up that was probably made in the Far East. All relays are not created equal. Most of our relays have a Diode within in addition to the contacts. The purpose of the diode is to absorb voltage spikes that can harm the various circuit boards within our 3. Re the heater, there may not be any circuit board in it but the fan speed control beside the fan contains a circuit board.
The jpg's below show a relay with an internal diode and also one with an internal resistor. The link following has more info on relays. That is why I say OEM as our 3's are alot more sophisticated than is first apparent. They are mobile computers first and the worlds best 4x4, second. https://www.accessconnect.com/car_relays.htm
