Heated seats
The seats in my 99 RX 300 are heated. The driver's side seems to get very warm, cool down, then get very warm again, then cool down, repeating the cycle. I was in my dad's Buick with heated seats the other day, and they stayed a nice constant temp.
Is my RX 300 normal?

Yes, that is normal.
There seems to be a regulator that turns them off and on at certain temperatures.
The '99 and '00 RX300's only have an on/off switch, so something like that is necessary to avoid getting too hot. In '01, they came out with a high/low/off switch which gives you a little more control. In the RX330, they finally went to an analog **** that is fully adjustable.

Welcome to CL, ChasRX! 
On my '00 RX 300 I had the same problem - it was most pronounced when wearing light clothing. Although I love the heated seats and wouldn't be without them, these carried "heat" to a new level. I occassionally expected to find grill marks on my nether region.
The 330, with its fully adjustable control is much nicer. I wonder if the control is the only difference, or if there is a thermostat in the heating element itself. What would be required for a swap, or is it even possible?
