99 Grand Am Cooling Fans Won't Work

The wiring to the front of the A/C compressor was broken (The whole connector) when the belt broke. Since then, the fans will not work. Took it to a repair shop and they replaced the computer (said that was the problem). When I got the car back, they said they temporarily fixed my A/C also by welding a wire onto the connection for the A/C compressor. The fans worked until the wire came loose from the compressor. Short of replacing the A/C compressor, how can I connect the wires to make the fans work?

I have a 99 Pontiac Grand am and first when i bought it i didnt know at first but wires for the cooling fans were hard wired and the car almost caught on fire so we tried to get new wires cause the fans...


if fuses are blowing then this is a indication the a hot wire is grounding out. Now as for the fan,alot of times what happens is that the sensor that tell the fan to kick on goes bad and someone wires them direct" Bad move " make sure there is no wires touching each other and that it is wired correctly and buy new sensor that controls fan. Auto zone will help you out and will also print you out a diagram as to the location and how to install it.....hope this helps and good luck...

Which cooling fan is the primary on a 99 jeep grand cherokee ???


The main cooling fan on this 1999 jeep cherokee, the main fan all depends.

These jeeps come with diffrent fan set ups. Here are a few, the first may be a fan driven off the motor by a fan belt and a another fan which is electric. the primary fan used for cooling is the fan that runs off the engine with a belt. the other electric fan is more the air conditioning system, this fan is used for cooling the condensor mainly. the engine driven fan is for the cooling system.


Another system fan set-up on these jeeps would be the motor driven fan by belt with another electric fan in front off it, the diffrence between the first and this one is that the first fan system is side by side and this one is set-up one in front of the other but the concept is the same, the fan driven by the engine is mainly for the cooling of the engine coolant and the electric fan is for air conditioning cooling.

In both set-ups the electric fans also help the cooling system but are mainly used for the help in cooling when the a/c is turnned on, the a/c condensor builds up heat the same as the radiator does, one fan is unable to cool both the radiator and the condensor, this is why some cars have two fans.

Good day, hope this is helpful,

Ac swith on copressor do not work


If the AC switch on the compressor doesn't work, then the system is likely low on refrigerant and won't operate it to reduce the chance of damaging the compressor, due to a leak in the system.

99 chev malibu,cooling fans dont come on


make sure it is full of coolant, next check for a bad fan relay, to see if fans are ok! run a wire from positve post on battery to positive on fan motor, ground other side if need be. if fans do not work they are bad, if they do work, check relay to fan and coolant tempurature sensor if needed.

The fans are turned on by the PCM, if the PCM is not telling the fans to turn on, they won't even if everything tests fine.

99 dodge grand caravan a/c not working.compressor cluch working,fans don't come on lines hot down at compressor


Cooling fans must work with a/c on.With a/c turned on check voltage at fan motor plug.If no voltage have to back trace to fuse for fans or relay's,but I have replaced a few fan module's for this problem.

If compressor isn't kicking in, check the connector atop the a/c accumulator, beside the coolant recover tank, in the engine compartment. That connector is atop a black bottle, and the connector goes to the low pressure switch. These switches do fail, and you can jump a wire across the connector terminals to see if the compressor comes on (engine running). As this circuit provides part of the ground path from the compressor clutch, if the switch is open, the compressor will never turn on. If the switch is failed, it can be replaced without opening the a/c system. Just disconnect the connector, unscrew the switch, replace it, and reconnect the connector.
