you can buy a chilton or haynes manual at a parts store, or on ebay. Sometimes on ebay they sell the diagrams that are emailed to you in an ebook as well..

You may have vapour lock in your heater lines. Start engine, put heat lever on high, disconnect one of the lines on your heater core, the one on the flow out side, & see if you have any air coming out. Once antifreese comes out stick line back on & retighten clamp. Make sure your cooling system is topped off. Also your water pump may not be functionihg to it's maximum. Take rad cap off cold & view flow rate. If inadequate you may have to replace the water pump. Good luck!

Hi, the speed sensor is powered by the PCM via the 10 amp fuse labeled IGN E under the hood. I don't believe your problem is the fuse, as the truck would not likely run if that fuse was bad. The more likely problem is with the speed sensor itself. Sorry I do not have a test procedure for this sensor, so I can't guarantee a new sensor will solve the problem. What you can do is while the truck is jacked up with the drive wheels off the ground (use 2WD), use a voltmeter to back-probe each terminal of the sensor with a voltmeter (put the other probe to chassis ground), and check the voltage with the car running in park versus running in gear. One of the terminals will have a reference voltage and the other the signal. If the signal changes with speed, the sensor is probably working, and the problem would then more likely be the instrument cluster. Let's hope it isn't the cluster, because they are more expensive. A new sensor is just $22 at Autozone. I have pasted instructions below for replacing the sensor. Please let me know if you have questions, and thanks for using FixYa.

Removal & Installation
CAUTION Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
