Question about 2003 Chevrolet Silverado 2500HD

Open Question

I have a 2005 Chevy Sliverado 2500 HD durmax. the drivers side heated seat will come on intermittently without touching any controls. The unboard computer has been reprogrammed no less than six times for this problem. (Chevrolets solution) to noavail. Chevrolet just wants to continue reprograming the computer as it never throws an error code. Any help solving this problem would be greatly appreciated. The seat gets damn hot in the summer months

SOURCE: A/C and Heat Driver Side Intermittent Problem

You will need to replace your driver side temp actuator. It is most likely sticking or over travelling. It is located under the dash directly below the a/c control head. It is bolted to the a/c box upside down with two small bolts. Let me know if i can help more.

By looking at the schematics, I would have to point towards the module if both seats have at the same time. If you can't see the wiring diagrams, email me at iambanshee74@yahoo.com

Have you checked the fuse? Look in owners manual for the fuse block and see if the fuse is burnt.

Here is a heated seat TSB for cars built prior to 12/14/07

BEFORE 12/14/2007

FORD:
2005-2007 Five Hundred, Freestyle
2008 Taurus X, Taurus

MERCURY:

ISSUE
Some 2005-2007 Freestyle, Five Hundred, Montego and 2008 Taurus, Sable and Taurus X vehicles built before 12/14/2007 may exhibit an inoperative heated seat(s). This concern may be caused by an intermittent open element in the heated seat mat.

ACTION
Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE
The heated seat system is controlled by the heated seat module located underneath the front passenger seat cushion. The heated seat switches are part of the heating ventilation air conditioning (HVAC) module but the heated seat system operates independently from the climate control system. The heated seat module regulates seat temperature by monitoring resistance of a thermistor type thermostat located in the cushion heater mat. The heated seat module is designed to remain on, heating the seat and maintaining temperature until switched off. For vehicles built before 5/1/2006, the module will time-out and switch off after 10 minutes.

1. Refer to Workshop Manual (WSM), Section 501-10 for pin point test on inoperative heated seat(s).
a. When testing the heater mats resistance and circuits for an intermittent open, technicians should sit in the seat while testing the circuit resistance, move the seat in multiple seating positions and apply pressure to several areas of the heated seat mat to ensure the mat element is not open intermittently.

2. Refer to WSM 501-10 for heated seat element replacement when an open electrical circuit has been identified.

Parts Block
WARRANTY STATUS: Eligible Under Provisions Of New Vehicle Limited Warranty Coverage
IMPORTANT : Warranty coverage limits/policies are not altered by a TSB. Warranty coverage limits are determined by the identified causal part.

OPERATION DESCRIPTION TIME

I hope this helps to solve it.

Heated, power seats not working


Check wiring under the seat. Frequent habit of pushing things under the seat such as flashlights and tools etc and moving the seat forward and back sometimes pulls wires or breaks them.
