1996 Plymouth Voyager heater valve location ?
If there is no heater control valve visable on heater hoses ,then it does not require one. heater core could be stopped up. flush the inlet and outlet with a water hose,and bleed coolant system.
1990 plymouth grand voyager, acts like a bad alternator but replaced 3 times, replaced control module once. still drains battery.
What is battery voltage with engine running? How long does it take to drain enough to prevent starting?
A 1990 Plymouth will likely not have parasitic power requirements. With ignition in off position the battery current should be zero (0.00 amps).
So using a current probe or shunt, with ignition switch in the off position, systematically remove fuses to identify the circuit draining the battery. Likely you'll find some after market add on (radio etc.) that is not installed properly.

1997 Plymouth Voyager left blinker, radio ,blower 4 air conditioner not working
You should have fuses for them and probably relay for blower . Check fuses, relay and check for power to your equipment. Check the bulb, power to and ground at the bulb. Check fuse to radio and power to radio. Check blower relay and fuse if it has one and power at blower. Did all this go out at the same time. If they did was some work going on which could have created wiring or short in wiring issues. The link below is for a 98 but some of it may be the same. If you have question about which fuse check them all but if you pull them out do one at a time. Try running the blower motor in all setting, sometimes the resistor will go out and the blower may only work in the highest setting.

1981 Plymouth Reliant starts right up...Idles great....Give it gas back fries through the carb....even when driving down the road...After the back fire starts to idle rough....
There are many reasons why an engine should spit back through the carb. I once encountered a Ford that had a worn exhaust lobe on the camshaft so the valve was barely opening - the engine ran very well until the throttle was opened. It is still a huge mystery how the owner had managed to drive it to my workshop.
The most common reason is a lean air/fuel mixture caused by one or more carb jets being blocked.
A thorough carb clean is a sizeable task that shouldn't be undertaken lightly and it is best practice to tackle it last after ensuring everything else is as the manufacturer intended it to be - from spark plugs and spark power/quality, timing, valve operation, fuel delivery quantity and pressure, etc., etc.
