2001 Chrysler Intrepid BaseFACTORY OEM SERVICE PROCEDURE
Driver Seat Heat Output Open
NOTE:
After making any repairs, perform MEMORY SYSTEMS VERIFICATION TEST
under VERIFICATION TESTS.
- Turn ignition on. Raise driver seat to highest position to gain access to seat components and connectors. Turn ignition off. Disconnect Memory Heated Seat/Mirror Module (MHSMM) connector C3. Measure resistance between ground and MHSMM connector C3 terminal No. 12, driver seat heater B+ driver circuit (Red/Dark Green wire). See Figure . If resistance is less than 8.5 ohms, replace MHSMM. If resistance is 8.5 ohms or more, leave MHSMM connector C3 disconnected, and go to next step.
- Disconnect driver heated seat cushion 4-pin connector. Measure resistance of driver seat heater B+ driver circuit (Red/Dark Green wire) between driver heated seat cushion 4-pin connector terminal "A" and MHSMM connector C3 terminal No. 12. See Fig 1 . If resistance is less than 5 ohms, leave driver heated seat cushion 4-pin connector disconnected, and go to next step. If resistance is 5 ohms or more, repair open in Red/Dark Green wire.
- Disconnect driver heated seat back cushion 2-pin connector. Measure resistance of heated seat driver circuit (Brown/Black wire) between driver heated seat cushion 4-pin connector terminal "B" and driver heated seat back cushion 2-pin connector terminal "A". If resistance is less than 5 ohms, leave driver heated seat back cushion 2-pin connector disconnected, and go to next step. If resistance is 5 ohms or more, repair open in Brown/Black wire.
- Measure resistance between ground and driver heated seat back cushion 2-pin connector terminal "B", ground circuit (Black wire). If resistance is less than 5 ohms, go to next step. If resistance 5 ohms or more, repair open in Black wire.
- Disconnect driver heated seat cushion 4-pin connector. Measure resistance between driver heated seat cushion connector (component side) terminal "A", driver seat heater B+ driver circuit and terminal "B", heated seat driver circuit. See Fig 2 . If resistance is less than 2.5 ohms, go to next step. If resistance is 2.5 ohms or more, replace driver heated seat cushion.
- Disconnect driver heated seat back cushion 2-pin connector. Measure resistance between driver heated seat back cushion connector (component side) terminal "A", heated seat driver circuit and terminal "B", ground circuit. See Fig 3 . If resistance is 2 ohms or more, replace driver heated seat back cushion. If resistance is less than 2 ohms, fault may be intermittent. Check related wiring and connectors for poor connections or damage to wiring harness. See WIRING DIAGRAMS . Repair any problems found as necessary. If no problems are found, check if any Technical Service Bulletins (TSBs) apply to vehicle. If no TSBs apply, test is complete.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
