Re: light blink

Chances are it is the dimmer switch. Not a uncommon problem with ZJ's

There was a thread over at JeepForum about this, but the pictures in it are gone now. :-\

Anyway, I had this problem and solved it by removing the switch assembly, taking it apart, and simply resoldering ("reflowing") all the connections on the PCB board. You can try to clean the dimmer slider with alcohol while you're in there, too.
Basically what happens is that 15 or so years of driving vibrations cause tiny cracks in the solder joints. Pushing on the switch closes the gap temporarily. Reflowing eliminates the cracks!
I've heard of some success using this method with bad BCMs and PCMs, too.


It really wasn't very difficult at all, took maybe 20 minutes once I got it out of the Jeep.

I reflowed all the solder points I saw on the board! But yes, it's likely the slider ones if you don't want to solder all of them.

Hello sanjuro

The weather here is getting hot and the other day temp reached 40C and my jeep got over 100C on the gauge
I replaced the thermostat from 91C to 72C and it's still reading 100C and sometimes more
I was thinking what if I changed the fan sensor on the upper hose is it going to make my jeep temp under 100C?

What do you think.

A lower temp thermostat won't necessarily keep your engine cooler, it will only cycle the coolant sooner. If the coolant doesn't have enough time to sit in the radiator to cool, it won't be cool when it cycles back into the engine, if that makes sense.
I'm guessing you already made sure your fan is working properly and that your thermostat isn't stuck, upside down, or backwards? How's your water pump?

Hi budy

T-stat is fine opens at 71C I guess
My water pump is new , installed last week
Low and high speed sensors work fine

What I really want is to keep the temp under 100C all the time on road and off road as well
Now I'm planning to but aftermarket radiator with wider straws I hope it helps cooling my jeep.
