1993 Blazer temperature gauge not working
Hi,
I have a 1993 Blazer. The temperature gauge isn't working. Is there a fuse in the fuse panel for the gauge or does it sound like a bad temperature sending unit? Thanks, Vinnie |

Re: 1993 Blazer temperature gauge not working
The coolant temperature sending unit is in the driver side cylinder head between cyls 3 & 5. It has a single wire going to it, if you ground the wire with the key on, the gauge should go to hot. Post your results.
