I have a 1994, 1/2 ton, 4x4 that has been causing headaches!
My ABS light came on... no clue beyond the sensor in the rear and do I really need to replace it
Cruise Control stopped working...
My 4x4 won't engage...
No reverse lights....
And the crazy vent/no heat thing...

Is any of this crap related? Please help me! I don't know where to start!

Thanks!

 

If your speedo is working correctly, the sensor in the rear diff will fix the ABS light.

The rest are possibly related, as they are all vacuum operated. (well, Ok, the reverse lights aren't......) Need to check for vacuum leaks. There really aren't that many vacuum lines under the hood, check 'em out, and see what you find. Also, the steel lines that run along the frame on the passenger side to the front axle are famous for rusting thru, check those as well.

Reverse lights...... if the bulbs are good, check the switch on the trans.

 

You make it sound so easy!! A project for when the snow melts and it warms up!

 

LOLOLOL

I hear ya on that one. but, wouldn't it be nice to have four wheel drive when the roads are crappy?

 

the vaccum line broke of my cruise control module under the battery and it caused the wild vent think. i fixed it and all is well.

 

Can anyone point me to a schematic for vacumn lines? I am learning as I go!
LOL
Thanks Guys!
