It always led back to the fan switch. Signed: Father with daughter attending school in another state. See the System Outline to understand the circuit operation. I'll keep this page updated. I checked the Engine Coolant Temp. If you do not properly ground or wire the new components, it can reek havoc on every electrical system in the car.
The actual wiring of each system circuit is shown from the point where the power source is received from the battery as far as each ground point. Joshthatcarguy answered about a year ago Have the same problem tried to earth it out to see if it would turn the fan on but didn't could it be anything to do with the relay, th fan turns on when i move the switch in the fuse box to the right and hole it there but turns off if I let it go. I was thinking it had a short and a bad thermostat forsure or waterpump. It is described on page 22 of this manual, and is installed on the instrument panel left side. Most cooling systems operate within 90 - 100degC.
Always perform inspection with the short terminal installed. Do not simply wait around for your vehicle to experience general. It is required to have enough room to take out the relay so, cut a hole 3 inches by 3 inches to allow you to pull the relay up to where you can remove the wiring harness relay wiring. When the engine is cold, the Engine Cooling Fan switch 10 is closed. The third character indicates a serial number used to distinguish between the wire harness combinations in cases when more than one of the same combination of wire harnesses exist e. May look like a 20 ga.
Keep me posted, be glad to help you get your car running 100% again soon. This insulation is lighter in weight and thinner than the normal insulation, making the wire diameter appear smaller than it actually is. See the temperature, if the Temperature go more than 199 F. They will test only by operating the key in the passenger door lock cylinder, not the rocker switch on the door itself. Also, the symbols that are used graphically give you information about components, connectors, or wires. Again, I appreciate your help. Once you located the relay, in the fuse box under the hood Try swapping it out with another relay and see if the fans stop, if the fans stop working with the swapped relay, replace the relay.
I pulled another thermoswitch radiator coolant fan switch from the junkyard and installed that in. This section is closely related to the system circuit. And Return to step 1. Given that these coolant temperature sensors meet or pass the technical requirements of their Original Equipment Manufacturer equivalent parts, they are very handy in stopping decline in performance and unexpected breakdown. Wire Identification Wires are identified by color and by the letters next to the wire. If there is no voltage, and you hear no click, the Cooling Fan switch 10 is stuck in the off position. For the past few weeks I've been having to put water in more frequently and I thought it may have been the radiator cap, I've had to switch out and it worked or the reservoir.
It has moved from year to year as it is prone to overheating which is probably why you're looking for it. Hey- the above answer is not completely accurate. This acts as a simple voltage regulator. Use Relay Location and Electrical Wiring Routing sections to find each part, junction block and wiring harness connectors, wiring harness and wiring harness connectors and ground points of each system circuit. However, if the switch is a multi-pole has more than one pin that is being switched , or gang type switch where the movement of the switch lever moves a number of switches open or closed , the symbol used on the wiring diagram can be more difficult to understand.
The second character indicates a serial number used to distinguish between the ground points in cases when more than one ground point exist on the same wire harness. I am guessing you have the V6? Also called a potentiometer or rheostat. I bought this car a month ago and lately it started overheating in stop and go traffic. I could be wrong but I am certain that the fans should come on at a certain vehicle operating temperature mines somewhere around 185-210 degrees Fahrenheit. Third, ensure the new thermostat was of the correct temp setting they all differ , so that it opens at the required time.
Since all System Circuit diagrams start from the power source, the power source system must be fully understood. Remove gently the left front headlamp. Any help is greatly appreciated. Fourth, make sure the radiator and associated hoses aren't blocked. I held the wiring in hand, while I heated the switch up with a mini hand held pen-size torch to see if the fans would come on. The fuse that controls the clock also controls the cigarette lighter.
Wouldnt want any dead batteries. It is on the the fuse panel located behind the dash to the left of the steering column. I cleaned out my two radiator hoses upper and lower since they had corrosion as well. In some cases the manufacturer does not allow us to show you our lower prices until you take further action. If on the other hand you pull the Radiator Cooling Fan Relay 8 out when the engine is cold and the ignition key is in the on position and the cooling fan is still running, then there is a short between Engine Main Relay 7 power contact and the Cooling Fan Motor 9 The video above is for an older Corolla. The code consists of the two characters: A letter and number.
