as my cruise control stopped working I checked for vacuum leaks. But I can not find some BUT there is no vacuum at my brake switch behind the pedal? Is this normal? Where can i go on searching?

This fuse is ok, they do not work in every situation. When I press the light button they do not work ass well

Automatic. I read somethin about a fuseblock in the engine bay but I cannot find it...

hello, my interior lights and the Radio (not original) stopt working, what fuse should I check? There is no 12V on where it should be constantly. 1990 Renix XJ

I searched for some PDF files I can use to check my cruise control. this is what I got: The switch on the turn signal lever is ok...checked it as it is written. I can not check the speed signal that comes from this little plastic thing under the dash at the speedocable? what is this?

today I changed: complete cruise control wiring harness brake switch (the white one) turn signal lever It is still not working !?!?!? How can I check the brake switch? Can it cause the problem? what is with the speed signal thing that goes into the wiring? How can I check that?

I tested the servo itself today. I diconnected the plug and put voltage to the orange wire and double ground to the both down in that plug. started the engine and the cruise servo directly started to open the throttle. I also checked the cables from the lever to the connection under the...

Hey I have the same issue. Tried the 4th t-stat yesterday but it is all the same. Temp goes up and falls down when the t-stat opens...on and on

I found this today when I came home and engine shut off. http://youtu.be/stVfcLxqPsE When I drive it the temerature goes from 70 to 100 and back to 70 and so on. Is it because of the bottle?

But they worked with the bad fuse?!?

checked the HZ/stop fuse, it was bad. changed it. what does it is for?

I checked the vacuum line to the canister and back to the servo. all fine. When I pull of the little line you can hear air coming in. The plastic piece at the end of the cable is connected to the throttle. than a big line goes into the firewall (no idea where) The cables at the level were broken...

gasket is the right one. I bought it from rock auto. I think it was air in the system. but the two holes let the water in the big coolant circle and will effect that the 195 dgree will not be reached when driving around.

fuel is not low at all! first pic is with running engine, second pic is shut off. at this point the gauges do strange things, Ttemp raises fuel falls down, I have no clue why

as I have some struggle with temp ups and downs I checkt the t-stat again today. drilled 2 small holes one at 12 and one at 6 o´clock as someone writes it is good. I put up the back so the temp sensor is the highest point. I put out the sensor and bottle open. I started to fill fluid into...
