    I have no heat in my passat 2001.5 model yr. This is a v6 30 valve engine front wheel drive. I changed the antifreeze , nothing, still no heat. I checked the water lines and are hot. The heater core has heat going trough. Place the climatronic control to high setting and get cool and cold pending on outside temperature. At times i get heat , but very minimal..HELP!! Before i replace the water pump ,v-belt and the thermostat..needd to know if that will solve the problem. I have seen lot of postings in regards to similar problem..the problem was not fixed in changing all of the above..

If you want to back wash just reverse the hoses on the outside where they connect to the heater core. if that don't work look on each hose and see if one of them has a device that has a vacuum line running to it . If there is this is a water shut off thats activated when the air con is on. temporarly you can just put a coupling in where the device comes out

Heater doesn't heat when cold

Chances are it is indeed the heater core as even a spent heater unit will blow hot air off the engine when the ambient temps are hot . When the temps drop, the heat from the engine block is not enough to heat the cab properly. Have you tried the old cardboard in front of the radiator trick? Speaking of semi's,ever notice they cover their radiators in the winter? That's because it helps get their block temps up a little higher and assists with heating as well. It's not much help but do the buyer a favour and let them know beforehand. Have a good one. :)

2002 dodge ram no heat

Do you live in an extremely cold region? If so, those folks usually have a problem with heater in winter time. With a fully warmed up engine, how hot does it get in degrees F? Are the heater hoses hot?

Both AC and Heat blow the same air.

Sounds like a flow flap or vacuum control head issue. The system uses 1 blower motor and one fan resistor. Both systems are intergrated to produce a BLENDED temperature. This means that to raise A/C temps originating at say 20 degrees to come out of the ducts at 45 degrees for cooling you need airflow through the heater core WHILE the A/C is on.
This is done with a blender flap. Hot air that is potentially matching the water thermostat (165 degrees) is expelled to blend with the 20 degree air to raise the discharge temperature to 45 degrees and up.
In winter, the A/C is engaged by design to keep the compressor lubed with oil. Usually this happens in Defroster mode, but through either Design or defect, may occur in heat position.
Now some of the Digital Climate control units have a Diagnostic sequence you can activate with certain button pushing combinations. Research Your Model, Year and then Climate Control Diagnostics on the internet. The sequence is something Dealers know about.
This Diagnostics would identify a malfunctioning Flap valve actuator.
I recommend people to visit a Salvage yard which allows you to dismantle a car yourself and see how the car is built.
Hope this helps and makes sense to you.

What is a ballpark figure for replacing a 2002 Ford Taurus thermostat?

stat is like 8 bucks,labor should not be more than 40 (at my shop)
worried the heater core may be the problem tho.
That is a very costly job.Try this,put a "winter front " on the
car,piece of cardboard in front of the rad.
I am assuming this car has no temp. gauge,so the winter front
will make the water temp go way up,if the heater works after like 5
miles of driving ,cool, the stat is bad,if the heater still doesn't work
the heater core is bad. The whole dashboard has to come out for the
heater core ,yuk
Don't drive more than like 20 miles with the radiator covered,just
to be safe,

My 2000 gmc pick up only blows luke warm air. Temp gauge show only around 170. I have clean the compartment air filter.

That temp gauge reading worries me. You might want to exchange the thermostat for a new 190F-210F thermostat (195F is good for summer, 210F really helps during winter). It should be a quick procedure.

Where is the thermostat located. I have no heat. Also the heat on the passenger side did not blow hot air last winter, only on the driver side, now none. Help!

If your temperature gauge and actual engine temp are normal and coolant level is full, you don't need a thermostat.(normal run temp is from 200 to 210 degrees. Likely your problem is a blend door not moving properly. Unfortunately, most controls on your heater box are inaccessible and the entire box needs to be removed (big job, get a manual or have a shop do the work)

your radiator could be getting stopped up. also water pump could be weak. during summer though you have electric fans that should be working. need to check. you can purchase some stuff called water wetter by redline racing oil that will drop water temp 20 degrees which is substantial when a thermostat is usually 180 to 190 and boiling is 212.

Previa Heater Problem

Previa heaters are usually ultra-reliable.
So, regarding your question, the only reason for the temp gauge to drop down with the heater on is the thermostat is sticking open, or you have a lower than recommended thermostat installed. The factory thermostat is a 192 degree F/89 degrees C stat. Down your way, a lot of the parts places vend the "summer" thermostats, and I suspect that this is your problem.
Look to see what the temp degrees that are printed on the stat. Should be 192 F or 89 C. The "summer" stats are 185 F/ 85 C. Also, make sure that your stat has a small "wiggle valve", some aftermarket stats do not have this. Very important. Install the stat with the "wiggle valve" pointing straight up/12 o'clock...
Regarding your trans dropping out od OD, this is because the coolant temp is dropping below 172 degrees F. This is the threshold for the OD to engage. Below 172/no OD engagement.
