Steam coming from the windshield wiper cleaner reservoir while the engine is running could indicate that the fluid is overheating, possibly due to a malfunction or a blockage in the system. If the engine is running hot, it can create excess heat in nearby components, affecting the reservoir. Additionally, a faulty cap or seal might not be holding pressure properly, allowing steam to escape. It's advisable to check the fluid level and inspect the reservoir and cap for any damage or leaks.
To clean water buildup out of a steam cleaner, start by emptying any remaining water from the reservoir. Then mix equal parts of white vinegar and water and fill the reservoir. Let the solution sit for about an hour before running the steam cleaner to clear out the buildup. Finally, rinse the reservoir with clean water.
Might be a bad heater control
you shouldn't have to, there should be a line running from the main reservoir through lord knows where to reach it. so if it's plugged or cracked.... well.
First listen to see if the pump located in the windshield washer reservoir is actually working. If it is not running, check the fuse and wiring. If there is power to the pump and it will not work the pump is defective and needs replacing. If the pump is working, then check to make sure the hoses running to the windshield spay nozzles are connected and not broken. If they are check the nozzle orifice to make sure no wax has accumulated. Clean out the orifice with a small straight pin or needle.
Because they are broken.
Refill the reservoir. Or, if full already, check the little rubber hoses from the reservoir to the outlets. If the checks out OK, check to Mae sure the pump is running when you activate the washer switch by haveing someone listen under the hood. No noise means the pump will need to be replaced or a wire is loose. If it is running and no fluid is being pumped it usually means that the impeller has come loose from the shaft for some reason and the pump will have to be replaced.
The truck needs a tune up.
There is no "reset" in the wiper motor. If your wipers do not park, it is likely your wiper motor parking contact or cam is broken. Try running the wipers with the key in the "ON" position, then turn the wipers off using their switch while they are up on the windshield. They should park themselves at the bottom. The good news is a wiper motor is pretty cheap at a junkyard, and not too hard to replace.
to cool the coolant in the engine
No
It's a standard item. Located under the plastic trim under the windshield wipers. Park the wipers so they are up towards the top of the windshield by turning the ignition key off while the wipers are running, then remove the plastic nuts or screws that hold the black plastic trim and vent piece between the wipers. You will see the cabin air filter. It is rectangular.
