Infiniti m35

Hello, the switch appears to thread into the block; I'm not sure what your question is. If there is a leak there, it's required to use a sealant like RTV silicone sealant to reinstall the switch. Other than that, I'd recommend some assistance from a shop near you. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
