So hello to everyone. I am recently new to the forum however I have been using it as a very helpful reference. So here is my issue.... no Speedo, no fuel level. I purchased a 99 classic in January and had a DVI done at a local shop I have handled most of the basic maintenance issues already. So my cruise control is inoperable, no Speedo, no horn, no gas gauge. Any advice?

 

Check fuses?

 

Is this for a 1999 XJ body Cherokee?

 

Do the dome lights still come on when you open the doors? I know it sounds like a weird question, but i had a similar thing happen when my gauges stopped working. There was a 10amp fuse under the hood that was the culprit.

 

I have already checked all fuses. Clock spring issue?

 

Yes 99 cherokee classic

 

Sorry, I didn't see that in your first post.

 

It sounds like a clockspring.


If you have a digital voltmeter you can check the 5 volt voltage supply to the sensors. A defective clockspring can bleed in excess of 5 volts in to the sensor supply voltage.


Uncouple the CPS connector, and with the ignition switch to ON, touch the body harness end of the connector at the pin cavity with the Orange wire going to it with the meter (+) probe (using the battery NEG post for the meter (-) probe). You should see 5 volts +/- .5 volts. If the voltage is too high remove the entire cover off the Junction Block fuse panel in the passenger footwell and unplug the Horn Relay - check the voltage again, if it returns to 5 volts the clockspring is bleeding the horn relay control coil voltage through the cruise control circuit to the 5 volt supply network.


If this is the case, leave the Horn Relay out until you can replace the clockspring.

 

Thanks for the advice I will look at this next. Soon as I have time to get to it. I will let you know how it goes.
