2002 Chevy Malibu

yes, had water pump and radiator replaced 5/2013

left turn signal not working

A/C not working


OK thanks for the information, have you checked the fuses to see if there are any blown fuses?
Customer: replied 4 years ago.

yes, it is not the fuses

ok first check the gauge by locating the temp sending switch and grounding the wire, turn the key to the on position and see if the gauge goes all the way to hot. let me know if you can't find it
please double check fuse #37 in the under hood fuse panel again. this is a known failure and has caused your symptoms before.

if it is # XXXXX what do i do? if it is a known failure, should the dealer be responsible? or what?


first replace the fuse and see if it blows right away, if it does you need to troubleshoot as to the cause. no the dealer will not be responsible.


known failure just means of all the repairs i researched that the most common was fuse 37 was blown. some times the circuits are designed to just handle enough amperage and as the car gets older more amperage is required to run the circuit and a fuse will blow
