There are others but you have to ensure they are compliant and say ALL MAKES. Also only use the same color if the radiator has the red coolant use the red coolant if it has the green coolant use the green. The dexcool was originally red and was for aluminum engines but most of the older vehicles that used it have been converted.
Check good voltage and ground for blower motor. Actuators under the dash may be restricting air flow? High speed doesn't usually use a resister.
Check for hvac trouble codes, in my part of the country, some of the national brand autostores will check codes for free, if there are any.
If you think problem with blower motor, itself, replace it. Sometimes, you can remove blower motor, use jumper wires for voltage and ground, using inline fuse, come off the battery, see if it blows like you think it should?
The fuse boxes is a location where power is being transferred from one line to another. All fuse boxes have harness plugged into them. Dismount the boxes and from the bottom side you can separate it out and can remount into a new box if need'. Consult a repair manual for the proper steps. Also have replacement on hand so you can see how thing unhook and remount.
This is a failure of the "remote function actuation module". It is located under the rear deck next to the right rear speaker. The rear seat must be removed to access it along with removing the rear deck. It controls the trunk release, door locks, dome light, and reverse light. My remote trunk release stopped working along with the relase button on the dash along with the reverse lights failing at the same time. The module is over $150 so I would try to find a way to rewire the lights to work without the module.
If it looks like chocolate milk then you will have a leak in the cooling system that is allowing coolant to escape into the oil. If your cracked radiator has been replaced and you check the coolant level you will find you will need to top it up.
(Take off the radiator cap when the engine is cold and you might also find evidence of oil that has escaped into the coolant and has attached itself to the radiator cap and the neck of the filler)..
White smoke generally occurs when coolant escapes directly into the combustion chamber not when it escapes into the oil passages in the engine and contaminates the oil.
What you need to track down now is where the coolant is getting into the engine oil which may be through a blown head gasket or a cracked cylinder head or both. If you had a crack in the radiator when driving the car the coolant will escape very fast because it is under pressure. Overheating the engine even for a short while can be enough to cause damage and heating up the engine is unavoidable unless you pick up the coolant leak very quickly.
The first thing I would be doing is to check for a failed cylinder head gasket because I would want to eliminate that as the issue if it has not failed.
In some engine designs coolant can leak into the oil via a failed intake manifold gasket and in that event it is a much simpler repair. I am not sure if that can be an issue in the engine you have fitted in your car but it is something you should check out..
In any event there is a very good video here on ways to identify if you have a blown head gasket. If you do not then you will most likely not have cracks in the cylinder heads either. But one way or the other you need to track down the internal coolant leak as engine oil contaminated with coolant will cause engine damage if not dealt with and the problem repaired..
