I changed the bottle and cap with new OEM parts, still having the same problem, so I changed the Thermostat and temp sensor (brass tipped) and the temp gauge is still going up. I also swapped the relay with the horn relay since they are the same # and the horn still works using the fan relay.
The cooling fan only comes on with the AC on, when switched off the fan turns off. I haven't let it go above 1/2 way on the temp gauge since I am afraid to do so. For the 6 years I have owned this vehicle the gauge has NEVER gone over 1/4, even when I lived in AZ for 3 years.
I have never noticed/heard the fan before since everything has been working, but when the temp gets past 1/4 and I turn the AC on the temp gauge goes down, so there must be a fan issue.
The only 2 other things I can think of are the PCM or the fan motor itself, but it works with the AC on!
Thanks in advance for any help!
have the same problem?
