Where is the fan relay located on a qx56 - QX56 Infiniti Cars & Trucks

System Description INFOID:0000000003533333 Control of the headlamp system operation is dependent upon the position of the combination switch (lighting switch). When the lighting switch is placed in the 2ND position, the BCM (body control module) receives input requesting the headlamps (and tail lamps) illuminate. This input is communicated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication lines. The CPU (central processing unit) of the IPDM E/R controls the headlamp high and headlamp low relay coils. When energized, these relays direct power to the respective headlamps, which then illuminate.

The fuel pump relay is an internal part of the IPDM (Intelligent Power Distribution Module). It is located behind the battery then behind the fuse box. I sits up right.

Well, on SOME of the Infiniti's for sure. I'm not sure about the QX56. Check your fuse box, fusible links/relays also. Here's a pic of the regulator with the reset switch. 2003 2005 Infiniti G35 Coupe Power Window Reset Procedure Infinitihelp...

I HAVE A 2005 INFINITI QX56, my cruise has stopped working, does anyone know what the cruise box looks like and where its located? I cant get any dealership to tell me or show me. Thanks

check the starter and celonid

There is an Intelligent Power Distribution Module (IPDM), a Fuse & Relay Box, a Fusible Link Box, and a Fuse & Fusible Link Box, all of which are located at the right side of the engine compartment.
Then there is the Instrument Panel Junction Block, which is located behind the driver's side kick panel.

The switch contains several copper pieces that can break from ware, and lay across making a constent connection

• You have a relay box under the hood back by the firewall on the passenger side. What happens is that fan relay goes out and the fan won't come on. When your AC is running the compressor is running and this makes your engine run much hotter than without the AC running. The fan should be on when ever the AC is on by default.
• So under the hood (diagram #2) is the relay panel. When you lift up the lid to the relay panel there is a diagram of all the relays and fusible links inside there. Find the relay for the fans and this should fix your problem.

sounds like you may have a blown fuse check the fuses under dash and under the hood. look in the owners manual

could be a main relay acting up or your cruise control module is in need of replacing also check vaccum lines for signs of deteriation or cracking
