When the vehicule is warm (ie leaving the underground garage) windshield washing liquid works fine. When driving on the highway during winter time, pression goes down drastickly. The liquid can barely reach the windshield. The first squirt is ok but after 1/2 second, the squirt is weak and it takes about 10 seconds 'till the liquid reaches the rear window... Liquid floes, but not strongly. No leaks under the vehicule. What's the problem?

The snow is starting to fall and the crisp, frigid winter air has arrived. I think that we can all agree that frosted windshields are a pain and having to go out to scrap the layer of ice off your windshield before heading to work in the morning can be the biggest pain of all. Here are some useful tips on 3 easy ways to defrost your windshield. Remember that it is important to take the time to properly clear off your vehicle before driving. Reduced visibility can be hazardous to yourself and other drivers on the road.
Cover Your Windshield-when leaving your vehicle, cover your windshield with a large piece of cardboard, a folded sheet or a towel. Remove the windshield cover when you are ready to leave and find that your windshield is free of ice and snow. There may be a thin layer or frost but the heater can quickly take care of that. There are magnetic windshield covers that are available to purchase online as well.

Ice Preventer or De-Icer Spray-ice preventer sprays can be sprayed on the windshield each night to create an ice-free windshield in the morning. De-icers are used to help clear your windshield when there is frost. You can purchase commercial ice preventer or de-icer sprays but you can also make homemade sprays as well. Fill a spray bottle with rubbing alcohol and add a few drops of dish soap, mix it well and then spray it directly on your icy windshield. A 3-to-1 white vinegar and water mixture will also work as well.
Remote start-remote start is a great feature to have in the winter and many new vehicles come with this feature now. Use the remote start while you are finishing up getting ready for your day and by the time you get to your vehicle it will be defrosted, warm and ready to go.

The sun roof has a drain channel that runs down the A post (between front doors and windshield) and sends water behind the fender. This can get clogged and back up. On my car there was a joint inside that separated, so the liquid would drain into the car.

Yes I am find to drive

You dont say if you have manual 4 wheel drive or electronic on the fly. Anyway, if you have the electronic knob, sometimes ice will get into the 4 wheel drive solenoid and cause it to not move into position. If you can get into a warm garage or underground parking for about an hour, you will see if it thaws and starts to work again.

your heater core is possibly stopped up if there has been a radiator leak and stop leak has been poured its definetly clogged or could be a faulty thermostat

You did not say what the outside temperature was, but is sounds like the washer fluid is freezing.

The most common problem I find in this season, is having summer 32 deg. F freezing windshield wiper fluid in the tank rather than -20 deg. F freezing windshield wiper fluid.

Try to warm up the car by parking it in a heated garage until the windshield wiper fluid thaws. Then, try to use it all up, and add the 'winter' vs. the 'summer' formula of windshield wiper fluid.

If this does not solve the problem, the pump might be burnt out, in my experience.

You should hear a humming sound as you depress the button for windshield wiper fluid inside of the car.

Good luck on this repair.

You can usually avoid that by using a good quality winter mix washer fluid that resists freezing, making sure the wipers are cleared of ice before beginning the drive and using the defroster to keep the windshield warm. In extreme conditions you just need to pull over and manually clean the ice off by hand.(only do that where it's safe). There are also specially designed wiper blades that will also help a bit.

Hi MeTV,

I was expecting to hear, 'And the radio only plays the theme from the twilight zone'. I'm glad you're an Engineer.

Process of elimination then:

• So temperature has nothing to do with it (Summer/Winter no diff).
• Not a switch (Different locations)
• Not a ground problem (Too consistent)
• Not even same circuits.

Maybe it's not so much the engine warming up as the length of time.

What's left are Fusible links. Self resetting fuses that may (and I'm reaching here) be popping during startup. They take a few minutes to reset.

They are normally running through the firewall on the engine side. You will need a meter to check them. It has to be done while nothings working. They are regular wires with little barrel in line.

It's the only component that could be responsible

It can be worn distributor cap/rotor or coolant temperature sensor.
To check it leave car outside, try to activate if it is not use the hair fan and worm up the distributor cap area

If it helps replace the distributor cap/wiring/spark plugs. If it doesnot help warm up the coolant temperature sensor:

and, if no help, spurk plug area.
Also good idea in cold weather use higher octane fuel or regular with octane booster or injectror cleaner added and ask the mechenic to put winter oil (less viscous) for winter time during oil change.
Good Luck
