Question about 1998 Oldsmobile Eighty Eight

1 Answer

Where's the fuse for the AC on 98 Olds 88?

The AC works when a new fuse is in but then somehow the fuse blows and all the fan will blow is hot air. Put in a new fuse and it's cold air again.

So what does the fuse that blows, protect?

You need a wiring diagram & start to test
the components most likely to cause a high
current draw & blown fuse.

Don't keep replacing it.

You know the fan control circuit works, but the
compressor doesn't stay on. Did you monitor
the compressor as the fuse blew?

May have a module for compressor & fan
If so one side failed
The compressor clutch could be bad

SOURCE: 98 Olds LLC - AC works but fan air does not blow

If you have a late model GM car and the system is controlled electronically the blend door actuator becomes weak. When this situation occurs it will not move the air direction door inside of the heater/air conditioner plenum. in your case not to the vents Replace the actuator with new and recheck the system. i hope this helps

SOURCE: on my 1998 olds 88

the heater fan is what blows for a/c also. it may need a new resister for fan motor. the resisters should be under hood by the fan motor. just to the left of motor, one is for low speed and one is foor high speed. this is for a 98 olds 88. the resisters govern the speed of the fan, at differant settings. good-day!

No ac nd my fan stop working completely


Fuses blow because of higher than normal amperage in the circuit. Not sure what circuit the blown fuse is for but if it is for the fan the fan may be shorted therefore blowing the fuse. If you put fuse in while the ac was still on try shutting off the ac then putting the fuse in. See if it blows then if it doesn't then turn the ac on and if it blows you have at the very least isolated the system at fault.

Car overheats and AC stops blowing cold, then temp guage eventually goes back down and AC starts blowing cold, after a while overheats again and AC stops blowing cold again. problem just started after a...


Your AC system is supposed to shut down if the engine is hot, as a safety device-make sure when the ac is running , the radiator fan is blowing-it may not be, caused by either a bad relay, blown fuse or a bad fan motor. Make sure your antifreeze is fully up to level, and if you haven't done it in the past 2 or 3 years, get the cooling system serviced with a new thermostat-cheap insurance, you do NOT want to overheat that aluminum engine, because if you do, it will be toast.
