2001 Cheverolet Express - with heater on, water sound in dash
Seems like I'm loosing fluid from the radiator, but never see any puddles or leaks. WIth the heater on, you can hear the sound of water in the dash in front of the passenger seat - but never see puddles under the car. What is the best way to see what is going on here? Temp guage looks fine.

Ask mechanic to put green anti freeze into your water and use a radiator pressure tester to find the leak while the car is stationary.The pressure tester is a bit pricey to buy for a one off test so radiator repair workshop probably best place to get test done.Green anti freeze is easy to see when it leaks,like a tracer dye.Good luck

a slow leak will not make the engine run poor, at least not a first. another spot hard to detect would be the heater core, behind the dash. when these leak you can sometimes smell it, kind of a sweet smell from the heater/ a/c dash vent area
Sounds like it's low on coolant. Check radiator. If low on coolant, heater may not get hot & temp gauge will read hot. The leak could possibly be a coolant leak..? Anti-freeze has a distinct odor when leaking from a hot engine. If that's the case, find the leak and have it repaired.
The condensation line can be cleared from under the passenger side of the car just behind the front tire, it can be done with a vacuum cleaner, But this doesn't sound like an ac issue, it sounds like the heater core is leaking.If you check your radiator fluid and it's getting low or that is the fluid in which you are talking about then this is the heater core and not ac related. The ac doesn't use liquid that is changable but rather a gas called refrigerant.
The ford focus and Taurus models from this period are notorious for water leakage. Unfortunately it can be from two possible causes. Lets start with easiest first. The water dam (black plastic) where the windshied meets the hood (on outside) sometimes pulls away from glass allowing water to run into the crack and then into the dash and into primarily passenger side. The fix for this is listed in a TSB by Ford and the dealer can install, for a price ofcourse, a replacement damn that helps. For my sons Taurus to diagnose if this was the true problem we put a piece of clear packing tape over the place where the dam meets the windshield making sure it was sealed to glass tightly and then waited for next rain and it was dry so that fixed it. SECOND possible cause is a bad heater core. If the wetness smells sweet like radiator fluid or sugary sweet then this is probably a coroded heater core that leaks radiator fluid into the passenger compartment. It is located in center of dash closest to passenger side. Unfortunately if this is the case it needs to be replaced and a radiator shop will charge anywhere between 250 to 500 to do the job with part included. If it is the HEATER core you should check your coolant level regularly because it operates on pressure and with a leakign heater core you can lose pressure and possible have engine overheating. Good luck
might be a small split or loose circle clip on a pipe, which would leak a little as pressure builds then lowers again. try letting your car run for 10 mins on a level dry piece of ground then look under it for any dripping or puddles or fluids.
are you sure it is water, smell it to ensure it is not antifreeze (smells sickly sweet), if it is antifreeze possibly heater core leak, otherwise check for plugged evaporator drip tube (with a/c of course), could also be leaking body panel (cracked chalking etc). hope this helps
it is the heater water supply and return, that supply water to the heater core to supply heat using hot water from the engine, the hose clamp my be loose or the hose has a hole in it you have to trace it from unner the hood fire wall to where it connects to the heater under the dash
