I've noticed that the heat is not real noticeable unless it's quite cold out (that was the original purpose !) so it might be that it's only a matter of perception that the heater doesn't work with the convertible top up. Have you tried it during cold (say <32 F) weather ? I was a little unimpressed w/ my "new" seat heaters Friday night (40 F out), but this morning (25 F) it was immediately noticeable and *very* nice.
I haven't found any good specific info on the thermostats -- I'd love to -- but it seems to me (I'm guessing here) that the system operates in cycles : a short time of full current (I= V/R, V=12 volts) until a threshold temperature is reached, followed by a "cool-down" period, possibly waiting for the temp to fall below another threshold, or maybe just a timer. The thermostat seems to be located in the seat back (b/c I've taken the bottom apart and it *isn't* there.) It would be great if someone with too much time on their hands could run some wires out from the thermostat and measure the resistance while the seat heaters are working. It's either a variable resistance (heat sensor) or an on/off switch (true thermostat). In the former case, the system could probably be "tricked" into running a little warmer by proper insertion of some series or parallel resistance. Otherwise another approach would be to physically move the thermostat a little farther from the heating element.
