Need help with truck not turning off accessories

I have a 1990 c1500. When I turn the ignition off and pull the key out. My heater illumination is lite up and says off. The heater doesn’t blow air and is off. But I can’t get the light to turn off. My wipers and my power window still work when the key is pulled. I replaced the ignition switch and I still have the same problem. Has anybody experienced this before.

Re: Need help with truck not turning off accessories

Would be unlikely. I have had the truck for 2 years and I never had this problem till about 2 weeks ago and Iím the only one that has worked on it and I never switched any wires around. I run a sperate fuse panel for all my other non factory accessories hot and ignition hot in my glove box.does anyone have anything else to possibly look look for.

I no longer have the schematic for this year. I think there is a convenience center module on these trucks with all the options like yours. Mine was a stripper truck so no fancy stuff in mine
