Very strange smell. Stumped

Waterloo, you have saved me once again my friend. This truck has about a 12 inch gear shift extension and one of those zippered covers. I would’ve never in Hell thought about checking it. Pulled the cover off and sure enough the damned boot has a hole in about the size of a quarter. I wrapped some rags around it and the smell all but disappeared. I’ll grab a new boot somewhere today. I’m still baffled because it only does it when it’s fairly cold outside. I’m thinking it’s always there but the cold air just makes it more noticeable. Thanks buddy!!!!
