Quite often changing the transmission fluid will correct such a problem especially if it is a high-mileage car.

I have the same problem with my '99 Vehicross. It used to work intermittently, but now it never works.

The first step would be to check the fuses. They are on the driver's side, behind a removable panel. There is a chart that shows what each fuse is for, but it does not identify the fan fuse But If they all check out good, that will eliminate he fuse as the problem.

The power to the fan comes from the ignition switch wiring harness, and it should be a blue wire. My problem started after I did something with the ignition switch, so when I get the time, that's where I will focus my attention. You'll have to pull off the plastic shrouding to access it. I don't have a wiring diagram, but I assume that the blue wire goes to the heater control switch. If you have power to the blue wire, then it could be in the heater control unit or the fan itself.

This should give you some places to start looking. I hope it's something simple like a loose wire connection. Good luck.

You will probably need some Ether based starting fluid. You may have to remove air filter to shoot a 2 second blast into the intake - but first try shooting the air intake with the 2 second blast and start vehicle. Diesel fuel tends to thicken in cold weather and a fuel additive like Lowes diesel fuel treatment may help keep your fuel fluid in colder weather. In cold weather, like on a night of clear skies causing low temperatures, a block engine heater will help to keep your fuel fluid - along with the diesel treatment. Block heaters are not too difficult to install depending on your vehicles configuration and how much room you have at a freeze plug, and are well worth the cost.
Hope this helps and please rate my solution!!

There is only one way to do it short of getting a crowbar in there. Get some coat hangers, if you have a cordless drill or a drill motor, twist the hanger in the drill a bunch of times to stiffen up the wire, then put a hook on the end and go fishing, get a light, and go to the left, try to find the catch and trip, it can be done. It might take you an hour, but it is the only way. Once you get it open, you can find out what happened to the cable. Might have slipped. Some cars have a hidden button or hole that you just punch the wire in and it will pop open. You have to look real close for it. One way to do it is get a van just like yours next to it so you can see what you need to hit. Hope this helps.

here goes for a 1 Tu. this sensor detects detonation in the engine caused by a dirty piston head dirty valves and valve train. When it detects this detonation it tells the computer to ****** the timing so it does not burn a hole in the pistons, at the same tie it tells the computer this the computer adjust the fuel mixture ratio to decrease hot soak detonation which can occur after running the engine getting it hot and turning it off for 5 minutes and causing the gas to pre ignite due to the heat of the engine. This device is made of piezoelectric material which generates a voltage due to sound running threw the knock sensor, Ceramic disks wafered together and it has a preset low and high voltage low voltage is 1.0 DC VOLTS high is 4.0 volts dc WITH 5 VOLTS DC as a reference voltage for testing purposes. to see if it is working tap near the knock sensor and if it is working you will notice a variation in the running of the engine as it changes timing and fuel mix to stop detonation.
