Moderating steering wheel heat

Sun Feb 09, 2020 11:18 pm

I find that when I use the heated steering wheel on my new-to-me 2015 SV, I am forever turning the wheel heat on and off. It gets uncomfortably hot when just left on. I understand that it's supposed to be thermostatically controlled; I suppose that could be stuck in the "on" position.

Has anyone ever tried to modify their car to provide a knob to turn the steering wheel heat up and down?

No. There are several topics on this, and the only way to moderate the heat is to turn the heat off before it shuts off automatically. This "short cycling" allows you to turn it back on whenever needed, because there is no delay if it hasn't reached its max temperature. Using a rheostat is an interesting idea, but I suspect it would be harder than it sounds to implement.

I have a friend who is a genuine electrical engineer. I'm going to ask him if he can design a simple circuit that would cycle the power to the steering wheel on and off say once a second, with adjustable duty cycle.

I think that a simpler way would be (via a resistor?) to tell the existing relay that the shutoff temp has been reached while it is actually lower.

Most people complain that the heated steering wheel does not heat enough...

I have always found that the steering wheel heats up well in the first 10 minutes, and then turns off. There is no control to continue the heating. Other than turn it off and on??

Correct. There is a cool down period of several minutes or more if it turns off on its own. There is no such wait if you turn it off while it's still heating.

I think if you waited long enough you'd find it would eventually turn off, right before your fingers melt to the steering wheel :shock: then it would get almost cold before starting all over. If you can find something simple to give a more warm all the time solution, it would sure be nice. This has been going on since '11 and every year Nissan fails to address it, it's like they just don't care, never use their products and don't read sites such as this :roll:
Note I believe I've read the most recent Leafs may have finally addressed it but I'm not positive.

Could well be, I haven't even tried to look up a circuit diagram. Are such diagrams available? I have to admit I'm spoiled from working on my motorcycle, where I have diagrams for everything on both paper and electronically. And sometimes they're even accurate. :lol:

Yeah, I've only had this car a couple of weeks, and I live in Denver. Contrary to popular belief, winters are pretty mild here. Those folks in the upper midwest or Canada are dealing with a lot colder weather.

They must have addressed this issue because my '18 SL the steering wheel heater never shuts off on its own & I have not needed to shut it off when the ambient weather is below 50F due to the wheel being too hot to comfortably hold.
