The '86 had thermostatic heated seats. The thermostat is a dime-sized disc just to the right of center under the cover. Have a look at the Bentley "early- without rheostat" wiring diagram and check grid continuity first.
(You will have to have cold seats otherwise the thermostat won't be closed. Mine are designed to close around 58 degrees (Fahrenheit, sorry), others are set differently. Also check for 12 volts to the connectors with the key switched on and the fuse intact.)
If you have a break in the wires, pull off the seat cover (half an hour for the first time, not bad) and locate it. Solder the break(s) back together. Sometimes there will be a dark or burnt spot where the break is, other times you have to get creative with the meter.
If your grid is still intact, or if you've fixed it and the seats still don't heat up, the thermostatic switch is most likely at fault. They're pretty cheap if you value this function, and like all thermostats, they wear out with time. When you replace one of these, be sure the connectors are still firmly-attached, otherwise one will pop off the first time you sit down. Also be sure the connectors have not been bent out of shape; one of mine bent and split off of the wire and punched through the seat cover.
After this is done, plug the seat back in, check for continuity on the grid (around the thermostat), and cover the break in the burlap-ish mesh (how you got the thermostat out) with fabric tape. I used cloth tape from a bicycle rim strip, although most people don't have this laying around. It's probably gotten plenty warm inside from your working and soldering and such, so leave the windows open or leave the car outside overnight and fire them up in the morning. Check for continuity of the grid (it'll be there if the wires are repaired and the thermostat is closed) and take her for a test drive. I repaired the seats in my '88 a couple of years ago. One side was a broken grid, the other was the thermostat. Now that I got rid of the autobox, heated seats are really the only feature on the car except for the (turbo-level) radio and equalizer.
Then this summer I saw a few Scaabs on the delivery truck (I worked at a Volvo dealer) and noticed a base model 9-3 with heated seats optional. Tsk, tsk, tsk. Too bad, really, when you consider that they were STANDARD on the 99 beginning in 1972.
