Question about Oldsmobile Alero

1 Answer

I have an oldsmobile alero with a 3.4, and the two fans arent coming on at all. I have checked the fuses, and they are good. The fans arent even coming on for the air, or the defrost mode. I haven't checked relays, but there are three. one for fan 1, one for fan 2, and one for fan mode which i'm not sure what it controls. What do you think my problem is ?

The fan mode relay is the most likely problem,the other two relays use it to come on when needed,replace that relay,and see what happens,this should fix the problem,also,do not go by looking at the fuses by eye,use a test light,auto parts store sell them for about 4 dollars,cheap,clip the clip to a good known ground,turn the key on,and headlights on,and use the tip of the test light to check the fuses,touch both sides of the fuse you are testing,and the test light will light up on both sides if the fuse is good,if it is blown,only one side will light the test light.It is better way of testing the fuses,cause sometimes the fuse looks good,and is not.

The cooling fan and the air condition fan dont come on


Get the fan switch checked.If the switch is short, it will not let the fan to turn ON.Other possibility can be faulty fan relay in the engine compartment fuse box, under hood.You will have to check with meter for 12 volts. ----------- Thanks.Helpmech.
