Help fixing heated/cooled seat switch

[03EXPO4x4]

i have a 03 eddie bauer that has heated and cooled seats. My driver side works fine but for some reason the passenger side doesn't work, the button won't even light up... Any advice or common fixes for this problem? The girlfriend says its got to be fixed by winter haha

Where are the fuses at?

 

[Bedrck47]

Fuses #18 and #118 located in fuse panel behind passenger side kick panel

its just weird that only one side doesnt function or light up

 

[Bedrck47]

not weird at all each side is fused by both fuses but each side have their own control module.

can you read and understand wiring diagrams

check the connectors under the passenger seat to make sure they are secure. Have read reports that those connectors have come loose due to items being stored under the seat

If by chance you find a loose connection and it fixes the problem you can blame it on the girlfriend

ok. yeah i am going to get under there today and make sure everything is secured and clean. Hopefully that is the reason there is no power going to the passenger button

There was another post about heated seats on an 04 model and you did post there I also posted the wiring diagrams on that thread you should be able to copy them and they will help you as the prints I posted were from the 03 manual but the 04 is the same Keep us posted

If you look at the wiring diagram there is a ground connection for the Climate controlled
seat module, passenger side it is G201 and located behind the kick panel, RH side
Check to make sure it is a good solid connection
it is a black wire and should be connected to the sheet metal may be near the fuse block

Checked all connectors. Fuses. I found two black wires together grounded to the body right between the fuse box and door opening. Should I buy a new switch and see if it's the problem?

All climate controlled seats are inoperative
CJB Fuse F1.118 (30A).
Circuitry.
DEPOWER the supplemental restraint system (SRS). REFER to Section 501-20B . DISCONNECT driver safety belt buckle pretensioner C3201 or passenger safety belt buckle pretensioner C3202 of the affected seat and CONNECT restraint system diagnostic tool 418-133 to the safety belt buckle pretensioner harness connector. CONNECT the battery ground cable. CHECK driver CCSM C3031b-4 (or passenger CCSM C3036b-4), circuit 1153 (RD/BK) for battery voltage. REPAIR as needed. If okay, REPAIR ground to driver CCSM C3036b-3 (or passenger CCSM C3036b-3 and C3036a-9), circuit 57 (BK). Once the repair is complete, DISCONNECT the restraint system diagnostic tool from the safety belt buckle pretensioner harness connector and CONNECT the safety belt buckle pretensioner connector of the affected seat. REPOWER the SRS. REFER to Section 501-20B .

Neither one of mine worked on my 03 when I bought it in January. Long story short, had to have the modules (yes, there are 2) reset.
