Thank you for quickly answering my question! I have to agree with you on connecting the two lines. I have found that they use a resistor to voltage drop the low speed. I will tie the two lines together today and see what happens. Again Thank You!

Hello guys, I just yesterday had my radiator cooling fan replaced at a local trusted shop, but now it doesn't shut off. The mechanic is trying to find out why. It is a two speed motor and you can hear it change speeds. The relay is fine as the other components it controls are working fine. Thanks

Turn all accessories off. Turn ignition on. Verify that cooling fan is always on. Turn ignition off. Disconnect CCRM. Turn ignition on. If cooling fan is off, replace CCRM and recheck system operation. If cooling fan is still on, go to next step. 81) Check For Short To Power Disconnect cooling fan. Check voltage between ground and Power-To-Low Fan circuit, and Power-To-High Fan circuit at cooling fan motor wiring harness connector. If both readings are less than one volt, problem is intermittent and cannot be duplicated at this time. If any reading is one volt or greater, locate and repair short to power in Power-To-Low Fan circuit or Power- To-High Fan circuit. Reconnect all components and recheck system operation.

Any chance one of them is an aftermarket added-on fan? I double-checked the wiring diagram and they also only show one fan for the radiator and AC condenser.

Hold on. I just checked one of the web sites I use for reference a lot and they do indeed show a dual fan in one assembly. Can you see how many wires are in the electrical connector? If there's only three, one is a ground wire, then the other two could be one for each fan. I can't tell from the diagram if there's two motor wires or if they're a low-speed wire and a high-speed wire.

There's a relay box on the center of the core support over the radiator. It should have three relays in it that appear to be the same. Try swapping them around to see if the same fan still runs. That will tell us if all of them are okay.

The next thing is to measure the voltages on the two feed wires but that has to be done when the fans are supposed to be running. One is red / orange, and one is orange / light blue. If you find 12 volts on each of them at any time, yet one fan doesn't run, that motor has to be bad or the connector terminals are corroded.

Another trick is to remove the cover from a relay, reinstall it that way, then squeeze the contact. You can measure voltages at the motor that way or just see if the fan runs. That's easier than trying to figure out which wires to jump in the relay box to make the tests.

I really need help on this one, I have been at if for a while and I can't get the damn fan out of my 95 Lincoln Continental 4.6L with 211,000 miles. I got a new fan and it only has two screws but I can't get the whole assembly out.

My cooling fans run at high speed all the time. According to my manual I have a (VCRM). I have a fan motor going out and would like to fix fan speed at the same time. Temp. Gauge works fine. Runs cool. I believe a heat senor must send information to the VCRM but not sure. Fans start a second or two after car starts. Any hints. Thanks

Try replacing the coolant temperatur sensor and see what happens.

NO offense to Pro Master Rasmataz but if the temp. Gauge works fine and the car runs cool what good would it do to change the coolant temp. Sensor.

The CTS tells the computer when and when not to engage the fan running at high could mean the high speed relay is sticking
