i have a 2002 sebrings convertable 2.7 it keeps over heating i replaced temp sensor on the bleeder housing i replaced the relays and the electric fan wont turn on if i pull relay the high relay the fans turn on and theres no issue i found that the oil pressure switch is bad is there anyway that could be the issue? also i see on advanced auto parts web site they list 2 temp sensors but i cant find the small 1 wire one im guessing its on the block? any help
