SOURCE: 1992 es 300 lexus heater is blowing cold

. Yes it could. some are vacuum powered, cable powered (mechanically) or electric powered. If the valve does not open. The hot water will not get to the heater core. It could also be the thermostat not opening.

find your evaporator inlet outlet lines on the fire wall usually near heater core inlet outlet lines. then follow both lines until you find the one that goes to the compressor. that is your low side and the port should be on there

SOURCE: drivers side windshield wiper not moving

The bolt that holds the wiper on is loose. There is a little plastic cap at the other end of the wiper arm, the side away from the wiper blade. Remove the cap and tighten the bolt. That should get it going again.

No heate in my 1992 Plymouth voyager , remove radiator cap water not moving Not sure why ! Please help

Hard to see coolant circulating through the cap opening. If the engine is not overheating, the coolant is circulating.
To check the heater, first feel both heater hoses at the firewall where the hoses go inside. Both should be hot! If one is hot and one is cool, then the heater core is not circulating, and that is why you have no heat. If both are hot (with engine at normal operating temperature), then the heater core is okay, and the problem may be the heater case doors not operating properly. This is called the temperature blend door problem-common on lots of cars-and caused by either vacuum operated doors or by motor operated doors in the heater case not operating properly. Sometimes the doors break, sometimes the vacuum signal is lost due to leaking vacuum hoses, or the servo canisters not working.
In short, if the heater core is hot (if both heater hoses are hot), and the coolant level is not low, then the problem is probably the heater case. check if the doors in the case are working.

Why going down the road to see air conditioner blow out of the defrost vents on the windshield on a 1992 Plymouth Sundance 2.5 engine

Vacuum line to the heater controll box has a leak or is disconnected.

Or the controlls went bad.

I have a 1992 plymouth sundance i keep hearing a grinding nosie only when i push on the gas you could hear it and when you put it in reverse now it does it while im driving pushing on gas or not i hear it

Being front wheel drive you might want to check the engine mounts. When your driving it ,the engine will move because of the torque. this is normal . If the mounts are bad it might be rattling or rubbing on something .

Little heat in pass compartment!! Fan blows good. Heater door opens and closes properly. Engine runs at proper temp.

could be low on water or water pump could be week or your heater core could have a blockage.

Fan control relay

Quite often you'll find resistor on firewall, of passenger side under hood. 1-1/2"x3" block attached to firewall. In area of where heater hoses enter.

The heater core is up in, and under the dash. To remove it is a rather extensive job. I'd recomend a shop manuaul. The center consol, radio, heater control, glove box, and possibly part of the steering column will need to be removed first. The hoses on the fire wall in the engine compartment will need to be disconnected. If the unit also has A/C, there are a few other items to be considered.
