I moved the plug on large radiator fan and it started as well. It leaks coolant into the cylinders and causes inefficiency in the cooling system, leading to low coolant and overheating. It's usually best to start a new thread. Started new job after looking for 2 years and too broke for a rental car or dealer repairs. No idea what's going on, but I'm going to start a new thread about that. I was told to take the passengerside headlight out and cut a section away in the bottom and it should be right there. The thing about the part being defective.
Now start the vehicle and operate the accessory switch, the test light should illuminate, if not the switch or circuit ground has shorted. This didn't seem to resolve the issue -- the engine still overheats when at a stop. Helpful Information A relay is switch that utilizes an electrical trigger signal to activate. No luck switching the relays. When I plug it in, it springs back to the proper temp.
If it's bad then good luck finding one I never did for mine so I made one out of 2 single pole relays. This lead me to suspect the fans, so I tested the fans themselves independent dual electric cooling fans. They can be pretty expensive. Watch out for relays from junk yards!! Release the red locking tab, pull out the socket, remove and replace the relay. The switch has now provided a path for current to flow through circuit 150 directly to ground. Now Follow Step 14 - 12 Change the relay.
They will be able to look over your vehicle and if necessary. Start your hole about 2 inches away from the vertical wall and center your cut on the trough. There are relays not just fuses for the cooling fan. I had a Neon with that problem that burned up its mechanical relay. I do not believe you can replace that unless you replace the fan. See if they come on when the ac is turned on,if they do,then the fuse is good,and the relay,and the fans are good,check everything else. I told him that I had read you could cut through the plastic and I didn't want that done.
This fan now has its own dedicated circuit and will operate at full speed. A few years ago my temperature gauge maxed out into the red on my 2001 Jeep Grand Cherokee. Does the scan tool indicate that this test passed? I remounted the relay to a better spot to replace if the need pops up. I notice the guy in the link posted above appears to have the post broken off the headlight and stuck in that same insert so obviously someone forced that one a bit. One thing that one mechanic told me is that a heat conductive compound should placed between the relay and its mounting location. I hope it's easy to reach. If I disconnect the temperature sensor, both fans come on immediately.
That is the easy part, the cost of a new one is the hard part. Both fans run together always. The cooling fan system in this vehicle provides for two separate modes of operation. I didn't have that much money so I drove home turning off engine at every stop and did some testing myself. Step 3 - With the wire strand secured in the relay terminal, attach the wire to a small automotive bulb and socket and ground. Remove the one screw holding the headlamp in place, pull out the whole headlamp assembly. You can touch the relay by reaching through the large hole in the back of the housing so determining where to drill isn't hard.
After some research and eliminating various causes I found out that the problem was probably the fan relay. If you think its a fuse or relay, could you mention which one or where it might be on the fuse block? I removed the wire connector thinking it might be dirty but was surprised to find that each plug was burned black on one slot of the female plug. I exchanged the temp sensor for a new one and installed it, and the cooling fans engaged. Your fan shouldn't run much at highway speeds and I suspect that's why you're putting way more hours on the relay than normal. These two operating modes are accomplished using 3 fan control relays. Now Follow Step 9 Now Follow Step 10 8 Check the connections at the relay. Dave Further to your comments 35charlie, Yes I do have ac and it does work fine.
I did the work myself and I am a third-rate home tinkerer -- it wasn't hard with a repair manual. I'll have to buy a new motor if it goes out again. In this particular case, the problem was that my new part was a dud. I guess nothing's impossible, though! Toaccess the relay here, the glove compar … tment might have to beremoved. Dave I just replaced the relay this past weekend.
Try swapping the cooling fan relays and see if the fan starts to work. Now Follow Step 14 - 11 Replace the faulty relay ignition feed circuit. Before starting any work on the relay I would make certain it isn't a bad electric fan. A relay is prone to failure when used for a long periods of time hot or when the amperage of the accessory has increased beyond its designed use. Now Follow Step 11 Now Follow Step 13 10 Mend the faulty relay control circuit.
The Relay shorted out-no big deal, I found out the relay is located below the passenger side headlamps. This can lead to overheating, especially when the vehicle is at a stop, where there is no forward motion by the vehicle to pass air over the radiator. I'd suggest starting it and letting it run for about 20 minutes, keeping an eye on the temperature gauge and watching for the fan to come on. I wired each fan directly to the battery, both function correctly. The dealer said they will look into and diagnose. Relay Identification Step 4 - Once the relay has been identified, gently grasp or touch the relay in question, have a helper turn the ignition key to the on position, then crank the engine over, the relay should click in one of the ignition switch positions.
