i've got a 2003 1500 ram the loaded version and with these heated seats the pass. side works fine but the drives side works on low but the high does'nt seem to work,at least thats what it feels like , now would it be the switch on the panel that would need replacing or would it be more to that?

 

The heated seat system, like everything else in the truck, has its own "brain" that controls all its functions. If the switch lights in the high position, the switch is ok.

The service manual has this to say:

and

Diagnosing the switches has a couple of pages in the manual so I won't put it all here. Odds are good that your problem is related to the element.

I've attached the self-diagnostics info from the service manual. If yours is exhibiting any of these behaviors, you'll know what the cause is already.

 

well i know there not flashing they never flash, it's just not heating up on high and think the low heat is ok ,the pass.side is ok it heats up really good. is the element eazy to get to from under the seat or are we talking something else?

 

the element is permantely attached to the seat so I believe it requires a new cushion. My passenger side is dead with low flashing on my 02. Heated seats useless feature.

 

I was going to attach this but there's a stupid 19k filesize limit for attached pdf's!

An option that I do not have or need

 

Any chance you might have the information on the heated seat module? I ohmed out the elements and everything looks good. The lights are coming on but I don't have heat to the driver side at all. I am assuming at this point its the module. Is there any way to diagnose it or should I be ordering a new one?

 

I sat in an 09 Laramie last week. Heated/Cooled Front Seats--heated rear seats. I asked the dealer what he'd give me for an 08 1500 (that i just bought from him 2 months ago). He just laughed and walked away

 

Did you check for voltage at the element with it powered up? perhaps it starts to heat and then expands and opens the circuit.

 

I gave up with my seat ohm reading all came back good on the passenger side and were exactly the same as the driver. As soon as I hit the switch flashing low light on the passenger side. Useless feature so I don't really care but like to have everything functioning.
