Heated driver seat problem

When i turn on the heated seat the light comes on for one second and goes right back off, and the seat never heats up. Is this a switch problem or the heating element in the seat and how do I trouble shoot? Aso unsure how much I am getting into taking the seat apart, looking for advice before I take seat out and have the car out of service.

    I have the exact same problem on my 02 bonneville. It is just the drivers seat that does it, the passenger seat works fine.

I just repaired one not long ago.It was a 2001 with heated seats.The first thing you can do is switch the switches to see if the problem moves to the other seat.There are at least three little heaters attached to the foam,that is bonded to the leather.One had a broken wire,the other two [that I know of in the base] tested good.Seems they all have to be working,so everyone must be tested for continuity,with out being pluged in to the others.The only way to see whats going on is to somewhat remove the leather from the seat. With extreme care I was able to get more wire out of the heater and soldier it back on.Then used silicone or 3m window welder around[I don't remember wich] to protect it as that is how it kind of it from the factory. It looked like the wire broke at the edge of the protective part due to sitting on the seat too many times. Bad design,to hold up over time.

Where is the fuse for the heated seats in a 2007 jeep grand cherokee laredo?


Remove the ignition key. Unplug the HSM (heated seat module). It is under the passenger seat. You can easily accomplish this with the seat all the way back. Wait a few seconds they plug it back in. Start the engine. Turn the seats on. If the indicator lights come on for 2 seconds and then go out, further diagnostics is required. Hopefully they'll stay on and the seats will be working fine.

Thanks,
Ron

2003 chevy avalanche heated seats wont stay on


The following diagnosis might be helpful if the vehicle exhibits the symptom s described in this PI. Condition Concern Driver and passenger heated seats inoperative or shut off in 30 seconds. There will be DTCs B2435, B2440, B3606 and or B1825 set in the Drivers Seat Module. The adjustable pedal position sensor, seat recliner position sensor and both heat seat thermistors share the same 5 volt reference internal to the Drivers Seat Module. A fault in any of these components circuits can make the heated seats inoperative or shut off in 30 seconds, as well as, the seat recliner and/or adjustment pedals may move in short increments when operated. A fault in heated seats, adjustable pedal or seat recliner will affect BOTH heated seats. Note Even if the vehicle is not equipped with adjustable pedals DTC B3606 still may set.Recommendation/Instructions To help isolate the area of concern use the Tech 2 and go to Sensor Data in the Drivers Seat Module. Monitor the following parameters for being out of range Recline Position Normal range .39V 4.58V Pedal Position if equipped Normal range .39V 4.58V Psgr. Seat Heat Sensor- Normal range 1V-4V Drvr. Seat Heat Sensor Normal range 1V 4V If a parameter is found to be out of range inspect circuits for any opens, shorts to ground, or voltage. If none found replace the suspect component Please be aware of the following common areas of concern The adjustable pedal position sensor internally shorted pulling the 5 volt reference low. Disconnect the adjustable pedal position sensor and see if the heated seats start working correctly, if so replace.Note Important The APP accelerator Pedal Position sensor is NOT the adjustable pedal position sensor. Make sure the correct sensor, adjustable pedal position sensor, is disconnected.The seat recliner position sensor internally shorted pulling the 5 volt reference low. Disconnect the recliner position sensor and see if heated seats start working correctly, if so replace.An open in either heated seat thermistor circuits signal or low reference The most common is the passenger thermistor where it passes through seat connector C305 pin L or K or C399 pins R or G A chaff to ground on either heated seat thermistor signal circuits. The most common is circuit 5475 black red or dark blue shorted to ground in the passenger seat near the buckle.Note Important The heated seat thermistors act differently to OPENS and SHORTS than the adjustable pedal position sensor and seat recliner position sensor. The adjustable pedals and seat recliner sensors can be disconnected for testing of the heated seats. Where as the heated seat thermistor circuit must be working correctly before EITHER heated seat will operate. Disconnecting one thermistor, which may have a concern will not allow the opposite heated seat to work correctly, BOTH side must be operational before EITHER heated seat will perate.Clearing DTCs If DTCs will not clear when using the Tech 2 after a repair has been made, try operating the device in which the repair was made. Example, if a repair was made to the passenger heated seat thermistor circuit, the DTCs may not clear unless the passenger heated seat is operated.Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed GM bulletins are intended for use by professional technicians, NOT a do it urselfer. They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle.

I have the same problem that is listed for the 2009 Torrent. My heated seats stay on for about 20 seconds then turn off and will not come back on. What's the fix? Thanks, Russ Sweet


Most of the time it will be a heated seat element thahed.t goes bad.But check your wiring under the seat first as it may become pinched.

Driver side seat heater light comes on and goes right out seat wont heat up passenger side works fine


The problem lies in the drivers side seat, the heating element for the back of the seat or the seat heating element has an open or shorted circuit. the part from ford will run you about $150.00 dollars.

1. Oil light comes on when car is standing still or not accelerating. The oil level is full. 2. Passenger side heated seat is not working. You can turn it on and it goes off in a couple of seconds.


The oil light problem is a faulty sensor or faulty oil pump itself. The Heated seat is a weak thermal switch or a short. You will have to test the circuits for the seat heater.

2005 hyundai tucson v6 passenger side heated seat will not warm up the light comes on. driver side is ok could it be the switch even if the light comes on


Possibly.... the only way I know to diagnosis this issue is with an amp meter in the circuit that heats the seats. Compare LH & RH seat heating current draw. If you find the pass seat is NOT drawing the same amount of current, further troublshooting is required. There are TWO heating elements installed in the seats -- seat bottom & seat back, and they are connected in 'SERIES'... so if either element goes/is 'OPEN', then it's component replacement time. There is a thermostat in the heating elements -- it regulates the seat temperature. One must isolate the two elements & check each one individually (seat bottom - checking resistance... and seat back - checking resistance). whichever one (or possibly both) are 'OPEN'. If you find resistance is normal (3 to 5 ohms), then the problem/cause may be in the switch (or its contacts). Using a test light (12 volt bulb), check for power (battery voltage) at the heating element connector to ground (chassis). If the bulb lights up, you know you have power at the switch and is sending it to the heating elements.

Silveraldo seat heater comes on


Look under the seat. If you have power seats the wire for that will run right to the seat switch. The seat heat wire will run from the on/off switch to the heater element in the seat. It sounds like you need a new heater switch.
I hope this helps.

Passenger seat won't heat


Hi my name is Allen!

The most probable cause for your problem is the heating grid that is mounted on the set for heating it, it is under the seat cover, the light will act weird because it is not completing the circuit. Raise the seat cover and visually look at it, it should be burnt.

For further asistance you may reach me at FixYa!
