probably switch, but check fuses and relays first. they are cheaper

the alternator operates those lights when its not running but the key is on you forgot a wire or the alt is po-poo

if the fuse is good i could be the switch itself take out one of the switch and check wires with volt meter

this is tested hooked up and looking for specific voltage as follows:
4.4v at100 kpa
3.2v at 80 kpa
2.1v at 60 kpa
1.1v at 40 kpa
0.5v at 20 kpa
the terminal has 3 wires a,b,c, a is ground, b carries the output signal to the ecu, and c is the 5v reference signal. while engine not running it register with about 5v.
happy holidays

Check the fuel relay in the fuse box they tend to burn out after a few years.. To access it. Remove the plastic cover by the cigarette lighter and remove the screw. Then remove the panel. This the big white relay on the left numbed 119 or 135. Replace it and see if this helps.
