The temp gauge on my car doesn't move. Stays at the cold position all the time. I removed the dash plate and when I touch the needle, wherever I put it, it stays. Also, when I turn my ignition on, sometimes the passenger side fan will run, sometimes both will run. After I start the car, both fans will run continously. Need some help with yet ANOTHER problem!

 

 

temp guage runs of a sending unit in the drivers side head, look below and between the first two spark plugs near the front, there should be a green wire clipped on to it.

are the fans running a new problem or has it happened right along?
could be bad relays, or something shorted to ground.

 

The problem just started. What should I check?

 

Check the relays and all the wiring, look on the radiator support near the battery for the 2 relays.
The primary fan is controlled by the ecm, the secondary is triggered by a switch in the pass head, seeing as both fans run all the time I would switch out the relays first, they're probably old and corroded

 

Thanks John...I'll try that out.

 

OK guys...got it working..I replaced the temperature sender (aka engine temp sensor) and it's giving me a reading! BUT, both fans come on within a minute...sometimes the driver side fan stops but the passenger fan continues non stop. If I disconnect the relays of course, they shut off. The relays are very clean and not corroded at all.

 

Anyone?

 

My fan never comes on at all, this is a good read... anyone else have advice?
