Locking clip suppose to be fairly loose, but if it's too loose it will not go all the way in to lock the axle in place, so you have to help it to slide in place.

Check the rest of your cooling system but It sounds like you need at least one electric fan since one is defective. It may just be a wiring issue, check this before you buy or replace Andy fans. Next, I'd look closely at the water pump, radiator, all hoses, heater core, etc. Also, check the engine oil and make sure it looks normal, again black or the "prettier" golden/brown color. If the oil is "Milky" looking or much too full, or if your radiator has an ugly substance itvit that'll also look "milky" then you're likely to have a blown head gasket. If you're suspicious of this, get a free Copression Tester from Auto Zone or a local parts store and Test each cylinder while recording the compression evens of each cylinder on a piece of paper.

Hopefully it's nothing major, and you can wire the fans to work all the time, whenever the key is on and if so don't worry as Mandy of us have done this before. Do some more troubleshooting to find the root cause of the overheating. You'll get it, just let us know if we can help further. The video below will show you how to get a god start on this problem!

Just replacing parts isn't the way to fix this problem , viewing wiring diagrams too see what all is involved in making the wipers work is . Then using a digital volt ohmmeter to test electrical circuits . Also looking at factory service info. to see how it's suppose to work.
Free wiring diagrams here http://www.bbbind.com/free-tsb/ Enter vehicle info. year , make , model an engine size . Under system click on body & accessories , then under subsystem click on wiper/washer . Click the search button ,then click the blue link. Looking at the wiring diagram i see two fuse's an two relays that are controlled by the BCM - body control module . Also hooking up a scan tool that can read BCM DTC'S - diagnostic trouble codes could be helpful . The wiper switch is a input to the BCM - the BCM will energize the relays to turn on the wipers.

Wiper/Washer System Components
The Wiper/Washer System consists of the following components:
• Windshield wiper/washer switch
• Body control module (BCM)
• Wiper 1 relay
• Wiper 2 relay
• Wiper diode
• Windshield wiper motor
• Windshield washer pump
• Windshield washer nozzles
• Windshield washer solvent container
• Windshield wiper arm and blade assemblies
• Windshield wiper transmission
• WIPER/SW 10A fuse
• WIPER 25A fuse

Wiper/Washer System Description
The body control module (BCM) controls wiper motor low speed operation. The washer pump and high speed operation are controlled directly by the wiper/washer switch. The windshield wiper/washer switch supplies voltage on the signal circuits to the BCM for windshield wiper/washer operation. When WASH, MIST, DELAY, LOW, or HIGH is detected, the BCM energizes the wiper 1 relay by suppling voltage to the relay coil. This allows battery voltage from the WIPER fuse to flow through the relay switched input then through the contacts and out the relay contacts to the wiper 2 relay switch contacts. Since the wiper 2 relay switch contacts are normally closed to the low speed circuit of the windshield wiper motor, the motor will operate at low speed.

I DON'T KNOW. I FOUND SUGGESTION TO REDUCE ALL TIRES TO 20 POUNDS THEN INFLATE ALL TO SEE IF FAULT CANCELS. DEALER WANTED $70 TO USE HIS METER TO FIND MINE. I DON'T HAVE AN AIR COMPRESSOR HANDY TO TRY THE AIR OUT/IN.
IF YOU ARE THRIFTY, MAKE SURE YOUR TIRES HOLD AIR AND PUT A BIT OF TAPE OVER THE FLASHING LIGHT. ASK TIRE REPAIR SHOP FOR COST TO REPLACE FAILED SENDING UNIT. PERHAPS WAIT UNTILL YOU NEED NEW TIRES.

With an oil pressure gauge:
Remove the oil sender unit and install an oil pressure gauge at the cold engine and let the engine warming up. And record oil pressure data.
You will see if the oil pressure match your problems if so then there is an internal leak or bad oil pump or old engine oil.

Hope it helps.

Many things could be your problem
1- coolant temperature or wiring defect
2- Cooling fan not working
3- Need to retrieve any engine faulty code with a scanner.
4- With a scanner look for any data that is not normal.
See a good auto technician

Hope it helps.

You need to know Battery Voltage is very important for PCM, Sensors and so on.
With a voltmeter on the battery terminal engine off, with a good full charged battery you should read 12.6v. If not the battery needs to be charge.
Clean battery"s terminals for a good connection and ground terminal body side.

Hope it helps.

Open the left front door and between the 2 hinges, you can see where are the electrical wires see if any wires are open circuit by pulling on each wire.
You will find your problems there.

Hope it helps.

You need to retrieve the BCM (Body Control Module) faulty code with a scanner. Fix any code that you find.
Try to erase any code and see if the problem is solved.

Hope it helps.
