Question about 1987 Oldsmobile Delta 88

Open Question

Fan doesn't work - growling noise when A/C Max button pressed tho

I took the fuse out of the A/C slot (#7) in order to cold air from blowing in my face. I could not get the heater to work. The indicator lights didn't work on the display panel for the A/C, heater, fan, etc. before the fuse was replaced, but when replaced, the lights came on, but then I was unable to get the blower to work at all... except briefly when the Max A/C button was first pressed. It made a growling noise, but soon quit. The heater seems to be generating a little heat, but of course it is not being blown into the car's interior.

The indicator buttons feel spongey, and doesn't really "connect." Nothing happens - no heat, no defrost, no A/C. I can move the fan indicator from low to high, but other than registering the chosen speed, nothing happens - i.e. no warm or cold air blows.

I would like to know where the blower motor is located, and how to test to see if a wire has become disconnected. (i.e. to diagnose, and fix the problem myself.)

I would like to disconnect the auto-start/door opener that was installed in my vehicle, because whoever stole it, is playing with my vehicle.

I would also like to install new locks in the doors and in the trunk to stop the perpetrator from stealing contents from my vehicle - i.e. battery, gas, etc...

I don't have a service/maintenance manual with my vehicle. It too has been stolen. If I can purchase one somewhere at a reasonable cost, that would be great.

In short, someone has been systematically vandalizing my vehicle, and I want to at least be able to do some trouble-shooting myself before being forced to take it to a garage.

Thank you very, very much.


P.S. I have given you my work email address, but my personal email addess is

SOURCE: Climate Control only blowing HIGH and remote not working

for the first problem, it sound as if the blower motor resistor has gone out. this is a very simple repair and the part does not cost very much. If you can locate the blower motor, the resistor should be on the left side of the blower motor.
for your second problem, it sounds as if the remotes need to be reprogramed.

I’m happy to assist further over the phone at

You might try treating it like a computer...reboot. Disconnect the battery for 20 minutes and make sure the cell phone charger doesn't have a cell phone in it. Surprisingly enough, there was a guy years ago on the old site who couldn't reset the codes on an OBDI vehicle and later found a cell phone on the charger which was back feeding the ECM enough the codes wouldn't reset.


dont rate it until satisfied

SOURCE: No heat in 1998 Olds Intrigue (daughters car). Please help ASAP!!

It sounds like a thermostat.... $100-$150 repair shop.........$20 part if you do it yourself !
Go to an auto parts store and have them read your codes to determine why the Check Engine Light is on and to confirm any problems. Advanced Auto Parts will usually do this for free!
Did you check the fuses usually located under the dash on the drivers side or under the hood?

Before going crazy with this, check all engine and body grounds to make sure everything is connected. it's possible something was left a bit loose when doing cylinder heads. Wont hurt to go over the positive battery and alternator connections as well!

Suzuki x4 2009 fan does not spin but when I turn air on it blows cold air.

Not sure which fan you mean. Engine cooling fan is different from heat/air blower fan.

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

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

Turned on interior fan speed and heard a loud noise, then nothing. Air speed now doesn't work.

More than likely the squirrel cage fan attached to the blower motor has broken or come apart causing it to bind up in the housing making the vehicle blow a fuse. Check the fuse block for the blown fuse then try the switch for the fan speed again if no noise, you may want to inspect the fan for damage.

I have a 98 Saturn SL1 that blows no air at all, the engines fan is blowing, and it looks like the serpentine belt on the compressor is running too, and when you put the car on max cold the rpm's...

Does your interior fan come on when you turn on the heat? If it doesn't, then look in the fuse panel for the comfort control fuse. If it is okay, then it will either be the fan motor or the comfort control switch.

My trail blazer has something in the front end that is really growling. it started out just a slight noise, now it is really loud!! I don't feel anything like a wheel bearing being loose, just really loud.

Had the same problem in my 2004 Trailblazer. Finally figured out it was the air pump on the driver side right under the driver side floorboard. Took it off and it was full off water because of a design flow by Chevrolet. I took the pump off and emptied the water out and dried it out real good and the noise stopped. I re routed the intake for the pump away from the front of the truck and haven't heard the noise since.

Aircondition not working....just blowing warm is working

Either you are out of coolent or the compressor is not working.

First check the fuses, then lift the hood and have a friend turn the air on. The compressor should cycle, if not take it to a mechanic. If it does cycle you are low on freon, take it to a mechanic for a system charge. Make sure they check for leaks first.

I presume you are talking about the blower motor and not the cooling fan on the engine?

If you have checked the fuse then ensure there is power at the blower motor when switched on.
