How does the seat heater work on a Saab?
However is there a relay in/under the seat which is operated by the switch on the ACC panel (I assume you have ACC and not MCC), and supply voltage from the fuse to the two heating elements, serial connected. Given you have access to the relay, you may feel it operates by touching it when you select heat “ON”.
Is there a way to check the current on a heated seat?
At the moment do I not see a way of checking the current, as pulling connectors will break the continuity of the “current loop”.

When do heated seats work on a car?
One guy said that they are thermostatic controld and only work when it is ccold. Is that right.? That’s correct, and the seats will (should) be heated when the ambient temperature is below 15°C (59°F), and the heat of the actual seat is lower than 20°C (68°F). Ground for the sensors (NTC Resistors) are common, and voltage supply is separate.

What should I do if my car seat fuse is blown?
When you begin the troubleshooting process, the first thing you should do is inspect the fuses. If a fuse is blown, replace it immediately. If that isn’t the problem, check the electrical plug underneath the heated seat where the seat plugs into the main wiring harness.
Are there any problems with a heated car seat?
Problems with heated car seats almost always occur in the seat heater element, instead of in the seat heater switch. However, checking the seat heater element requires taking the car seat apart, so you should begin by checking for other problems, working your way to the seat heater element as a last resort.
