I'm sure you could manage to measure the amount of energy wasted by your condenser fan, but I promise you it's statistically insignificant. If you're trying to save an amp or two or power, it would make more sense to make sure you don't have any lights on or that you're not carrying any heavy objects you don't need in your trunk. That said, the most ...

Get rid of the extra fans. If you're having to run fans constantly to keep the engine at the right temperature in the city, then all you're doing is masking another issue. You probably have several other issues. The engine temperature and the transmission going being able to shift into overdrive should be independent. It seems like you are conflating two ...

Replace the thermostat for sure, and while you're at it, replace the straight water with 50/50 antifreeze/coolant mix. Use the aftermarket fans ONLY during stop & go traffic in the city; on the open road they serve no purpose at all (ordinary wind from highway speed cools the radiator sufficiently in almost all cases). There's no need to remove the fans, ...

I did a bit more research and it looks like this link sorts my issue: http://www.blower-motor-resistor.co.uk/vauxhall-vectra-c-blower-motor-resistor.html

You have partially answered this yourself- you are seeing smoke, which implies the bearings are getting hot. So they could start a fire. Or in seizing up the fan could cause your wiring to catch fire. Or you could end up with a cabin full of dangerous fumes... etc You could do permanent damage, yes. Pay close attention and you might be okay. Personally, ...

If the fan is installed Check if it has any play by placing one of the blades at about 12-o'clock and applying light pressure in and out. (top goes toward firewall and the blade at roughly 6pm would push outward.) You should have very little play here. If the fan isn't installed then you can just grab the water-pump shaft _(where the pulley should be ...

It sounds like the blower motor has a significant mount of debre jammed into it causeing it be off-balance or possibly even broken a blade. Or, the bearing that it spins on is just worn out. Either way you'll have to pull it down and have a look at what's going on with it, it should be noticable either way. Either it has a significant amount of play in it ...

I take it the above picture of the fan/pulley on the vehicle is not your vehicle, but a photo of the same thing from another vehicle? If it is your vehicle, wrap a belt completely around either ribbed pulley part and hold it on one side to gain purchase (grab both sides of the belt in one place with one hand). Believe me when I say this will give you more ...

The two main things that would happen to engine with results as you describe. Easiest to check is the thermostat. The thermostat has a pin coming out of it which locates into the thermostat housing. The location of the pin breaks off and allows the thermostat to float, causing erratic temperature control. The second item is the water pump impeller. They are ...

I agree with the suggestion to fix the underlying cooling problem. Your vehicle should be able to handle tropical temperatures, even in slow traffic. I also agree with running antifreeze for the anti-corrosion and anti-boil properties. However, until you get the base problem figured out, you could continue to run plain water, as you may be having to do ...

I believe you can improvise over the approach shown in this diagram. Instead of using a spanner to 'lock' just one of the pulley bolts, try to use a long implement similar to the "special tool" depicted in the diagram to lock two pulley bolts in place. I have found great success with water-heater mounting brackets since they are thin enough and do not ...

It sounds like there is something between the blower and the heater core, maybe even on the core itself. It could just be leaves which have gotten sucked in and are now blocking it. When the blend door is is over to the cold side, it blows air just fine. Yet when the blend door is pushing across the heater core, it is greatly reduced. This leads me to ...

If the original motor was bad it may have blown the fuse, check the owners manual to find the fuse box and to determine which fuse powers the fan. If the fuse checks ok the next likely culprit is the resistor that allows the various fan speeds. I believe it is located behind the glovebox in your Cavalier. The next options would be the switch the wiring and ...

you could first check if they are getting any current with a multimeter or a tester. Then apply the appropiate voltage directly to the fan and see if it works, most fans work with 12v but if yours are in series it may be different, check the manual.

The factory electrical manual would be an excellent place to start, if they're still available for your car.

Sounds very much like a worn blower motor so you at least have to get at the motor to find out what it worn. While you're that deep in the car you might as well replace it with a new one.

My guess would be a blower motor resistor.

Have you tried some kind of penetrating oil? And possibly asking the parts store if there is a puller tool?
