Why is there no heat in my 1989 Plymouth Acclaim?
Low coolant? Bad thermostat? Heater core plugged, restricted, or airbound? ============================================================== Good answers by original poster. I would recommend replacing the t-stat first. Its pretty straightforward. If that doesnt solve your problem, our 89 acclaim's have a heater valve (it shuts off coolant flow to the heater core when the a/c is activated to increase the efficiency of the a/c) by the firewall that can stick or lose vacuum (broken vacuum line). Check that next. Lastly, I would take the lines off the heater core and run a garden hose up to it. This will "backflush" any accumulated crud out of the heater core. I do this to my Acclaim every fall and cant believe the crap that comes out! ============================================================== When the heater went out in my car, I went in and found out that it was the heater control valve. Check it out.

Where is the heater control valve on a 1999 dodge durango?
There is no heater control valve on this generation of dodges like there used to be... the water flows constantly through the heater valve.. the only control is a trap door that allows cab air to be run through the heater core and is controlled by a vacuum solenoid in the heater box.. the temp control is also vacuum operated but be sure to check the vacuum supply line coming in from the engine.... it has a check valve in it that can be keeping the controls from getting enough vacuum to operate properly.. if you don't have a mighty vac just get one of those packs of barbed vacuum fittings from your local shucks and bypass the valve temporarily and see if you get heat... hope this helps

How do you adjust the idle speed on a 1993 Plymouth acclaim?
It is not adjustable. It is computer controlled. If idle speed is incorrect you have a vacuum leak or a sensor/solenoid issue.It is not adjustable. It is computer controlled. If idle speed is incorrect you have a vacuum leak or a sensor/solenoid issue.

Heater control does not work on 1991 Plymouth voyger. fan operates normally. control stays on defrost only will not switch to any other function?
can happen when vacuum line is disconnected . look under hood to right of heater hoses. one vacuum line goes to heater valve (gate)on heater hose ,the other should go past this to a small sized metal object the size of a small lemon. if this is disconnected only defrost will work. I HOPE YOUR 91 IS SIMILAR TO MY 93.

How do you know if the master brake cylinder in a 1994 Plymouth acclaim is broken?
If it's "broken" then you have no breaks. More likely its leaking (internally or externally) and your breaks are soft, or need to be pumped. If it's just hard to break, check the power boost (a vacuum assist on most cars).
You did some work on the radiator bypass for your 2000 Ford Windstar 38L and now the vents inside the cabin won't change from defrost Is there a schematic showing you where you can look for the proble?
I am not sure what you mean by the radiator bypass. But it sounds like you have a loss of vacuum to your AC/heater control. When you have no vacuum to the control, it defaults to defrost. There is only one vacuum supply entering the passenger compartment through a black hose under the hood on the passengers side close to the AC lines where they go through the dash. There is also a vacuum canister right there. See if you have knocked a vacuum hose off right there.
