if in a jam, the radio shack or (mouser/digikey) resistors work.. i had some on a junk box and used these.
heater resistors
i used 1/2 and 1 ohm discrete resistors. in a hurry.

the glove box door comes out in 5min and the resistor block is there , 5min more.
never pull the switch first, but in OP, 's case, its already bad.
but yes, check the resistor as most are bad by now. the nichrome wire , just burn up, from age.
