Just a quick note that I followed the lead of the gentleman who used an updated Buick seat heating element for his 2010/11 SAAB 9-5. All measured resistance is in the allowed range 0,8 - 2,4 ohm (according to WIS) for back element and 0,8 - 2,3 ohm for cushion element.Ĭould you give me any advice how to proceed ? Voltage ? How could I measure the voltage ? I've read that the connectors must be plugged, but should be the car started ? heating switch turned on ? Should I try to measure the resistance with heating switch turned on ?Ģnd thumbs up on Buick heating element as hack for SAAB OE part the resistance was ranging from 1,3 to 1,7 ohm.Ĩ.

I've lifted the rear seat cover to be able to reach the connector of the back heater element (two wire connector with black/brown on one side - I suppose that this is the connector part of the element).ħ. I've tried to turn on heating with passenger bottom connector unplugged and the heating switch turned off immediatelyĦ. I've tried to measure the resistance today and both (drivers&passengers) cushion heating elements were 1,7 ohm (connector with 4 wires just under the back of the seat, measured brown and black, left two yellow intact)ĥ. 'By measuring current and voltage output to the seat heating elements every 10 seconds, the seat memory control module calculates that the heating element resistance is above the maximum resistance'Ĥ. According to WIS B2425 0D (drivers) or B2430 0D (passengers) is : I've got an MDI and Seat Control Module is throwing B2430 0D, which is 'Passenger Seat Cushion Heater Circuit - Open/High Resistance'ģ. The passenger seat is not working (last 2 weeks), it turns itself off after cca 1 minute. I'm trying to diagnose what's wrong with my passenger seat, but I'm stuck now.ġ. Thanks for everyone’s input on this forum!

The use of a large, sharp kitchen knife was helpful.Īfter it was all back together, voltage measures 7.1 v on the drivers seat and the heat is abundant. The most difficult part of this was removing the old heating pad and not tearing foam along with it. After some tedious work getting the leather off the bottom cushion, I was glad to see the original pad (see attached picture) had the same 12777552 part number.

I couldn't find the 12777553 pad for sale online so decided to take my chances with the 12777552 pad from eEuroparts. My 2011 9-5 Aero has sport seats with the leg extension but not ventilated. This confirmed that something is wrong with the driver’s side bottom pad. The passenger side measured around 5.8 v. Also, I measured the voltage across the brown and black wires (both bottom and back pads must be connected while doing this) and found it to be 12.7 v.

After further testing I determined the driver's side bottom heating pad had more resistance than the passenger side bottom.
