The Coolant Cir. Pump is located in the area below the battery and is controlled by relay #19 and fuse #41
With the, key off and with a new 10 amp fuse in place, remove the elec. connector at the bottom of the pump. Turn the key to the on position and with a DVOM, check the WHITE wire for 12v and the BROWN wire for NEGATIVE.
If both wires check out, reinstall the connector and then check fuse #41 and see if it is blown. If so, the pump is shorted and must be replaced.

Hi Maj.,
I checked the wires, they are good (12V and negative). Reinstalled the connector, checked the fuse and it was not blown. Started the car, checked fuse again and it's still not blown. I didn't drive with it yet, but I bet it would blow again...
Start the eng. and put your hand to the pump, do you feel motor working?
It's a bit hard to say if it's the pump really working or if it's the vibrations of the engin that I feel...
Though, the two big tubes get warm after the engin has been idling for 5 minutes...
And the fact of only starting up the engin doesn't blow the fuse. What could it be then that it blows when driving? The E-box that starts up at one point and is fawlty? Because the heater works...
No, miner's more simple then that. Just a push button for the A/C. It's a 2001 model. I'm at work now, can't make a pic and attach it. I can do it later on if you want. I hope the 2001 year helps for now...
(The pic that I send before in this thread says that that fuse is for recirculation pump, heater and E-box fan)
If it's this black part with numbers 29 and 088 written in white on it which is hidden underneath the 2nd cover of the fusebox, then it doesn't seem to work by putting the key to on position, nor when I start the car. The fuse 10A is still ok so far...
Ok, I checked the 2 wires. White is 12V and brown is grounded. The fuse is still ok.
When the e-box fan is on, does it make a significant sound and/or wind that blows. If it's supposed to, then it doesn't work
I felt underneath the fuse/relay box, where the tube with 3 holes of the fan ends, and I did feel ventilation, but it was extremely little...almost like nearly no wind... I hope that's the way it should be...
I took out the fan and it worked actually, cleaned it up a bit as it was slightly dusty, nothing bad. Plugged it back in and when it was upside down it worked a lot better as in its original position. Also it kept on blowing after taking out the key of the contact, maybe a security to cool down after haven driven the truck?
But all seems to work better now. Big thumbs up and thank you (again) Maj. Dundee...!
