SOURCE: 1996 buick roadmaster keeps overheating:

A shotgun approach to repairs can really rack up the bills.

If your symptoms are loss of water and you have replaced the thermostat, you more than likely have an issue with steam. And that steam more than often comes from a bad head gasket. Most head gasket gasket failures seem to be confined to the water side initially, but let it go on bigger damage will occur.
You can buy a litmus test strip to dunk in the coolant. It will indicate if there are exhaust residuals in the water and thus a gasket failure.

However it may just be something simple, given that you have just about replaced everything:

have you given the radiator a good hosing inside and out?
is the radiator fan running when it should be?

Only way to get smoke (steam) billowing in is a faulty heater core. It won't steam until the engine is warm. You should also be smelling an odor unless you have pure water in your cooling system. That vehicle requires the removal of the steering column and entire dashboard to replace the heater core.

SOURCE: heater fan speed control only works on 3,4 & 5

No, it is not a fuse problem. Most likely you need to replace the heater blower resistor. A replacement should be available at your local parts store, and they should be able to help you find it's location. If you follow the wires from your blower motor, they will lead to this component. Usually two 7mm screws hold it in the heater box, but might be 5.5mm (7/32").

don't forget to check starter, and ignition switch,otherwise i think John Parker is
right on the money.
I also think that if the shop couldn't find it they shouldn't charge you at all.

SOURCE: My 1996 Olds LSS doesn't idle properly,idling

Your first problem is to find out why the intermittent no-power problem. Honestly, that sounds like a loose conmnection somewhere. check all your grounds for clean and tight conditions Also, battery connections and alternator connections. Double check your power distribution center for any loose wires or poor connections. Once you solve that problem, then you can diagnose the other problems with poor idle and temp. gauge.

We have a '03 Pontiac Grand Am GT, 3.4L (3400).

If the resistor bypass doesn't solve it, another remedy could be a plug-in type engine block heater- I mean plug into household current. It keeps the engine coolant warm in the block. Every other car here in Montana uses one-works great for those below zero nights. When the wife pulls into work, just run an extension line and keep the car plugged in till time to go. Other than that, IDK, sounds like you've covered it pretty well as far as solutions.

I have a 97 dodge stratus. It won't start. Tried

Make sure it's getting fuel. Try using some ether or starting fluid. If it rumbles to life but doesn't stay running then there's a problem with the fuel delivery system. i.e.... Fuel pump, clogged filter, pressure regulator.... If the ether doesn't change the results you are getting now then it's a fire or sensor problem. Ignition coil, relays, sensors not signaling, PCM... I wish you luck. Let us know how it turns out

Why isn't my heater in my car getting warm

There could be several reason. The water pump could be weak. The radiator could be low on Anti freeze. The control valve on the heater line from the motor could be malfunctioning. The thermostat could be bad. You may even have an air bubble in the system that is causing the problem. The only way to be sure is to test each are. Check the fluid level and make sure it is good then run the vehicle till it warms up. With the vehicle running and warm locate the control valve on the hose running from the motor or radiator to the firewall, there are two. One will have the valve on it. You can open this valve manually and see if that allows the interior to warm up. If it does then the controller and vacuum lines to that valve. If it doesn't then remove the thermostat and see if that resolves the issue. If that doesn't resolve the issue replace the water pump.

First you need to purge the trapped air out of the system. Go to a shop that has evac/fill equipment and tehy can do it for about $75. It is ahrd to get air out. park uphill and rasie front of truck as high as possible, and keep cap loose during warm up. It will burp air. Then tighrten cap & let it cool while keeping the reservoir full during cool down. Repeat at least once. Make sure hose from rad to reservoir is tight at both ends to avoid sucking air in.

report results.

please rate if helpful

No heat is a sign of trapped air.

What is the best coolant for my 2001 Dodge neon? It is hot here where I live and I don't want anything to happen to the car/

any of the green or universal antifreeze will work... you have to mix a 50/50 mixture with water, the antifreeze isnt actually doesn't conduct the heat, thats what the water is for. antifreeze is only to keep your water from freezing in the winter, also to lubricate your water pump and is to prevent the water from corroding or rusting the inside of your engine.
