I had the same exact thing happen on my '89 Olds 88. It is the blower control module. Please don't don't confuse this with the resistor or relay, or even the delay module. It is simply called the A/C blower control module, and is usually located under a plastic flap, on the firewall, near the passenger side of the vehicle. I was a parts man at a GM dealership for 18 years and, if my memory serves my correctly, the GM part number will most likely be 12484912. It's not the simplest of operations, but if you have any mechanical ability at all you should be able to do this yourself.
Directly behind the engine, on the middle of the firewall.
In the engine compartment. Center of the firewall behind the engine.
My blower would blow cold air at idle & engine would start to overheat, I replaced my thermostat & problem solved.
It is in the middle of firewall between the engine compartment and the passenger compartment.
The replacement may have been bad. There may also be a problem with the relay from the AC blower to the fuse box.
It is on the far right (passenger) side of the engine compartment, attached to the firewall.
on the right side of the engine firewall on a relay brackt. which one?
Replaced many blower modules ( in engine compartment ) from that year. Check it out.
This likely is a problem with the blower motor module that is within the blower motor unit
The blower is common to hot and cold air. If it is only cold air that is a problem, then the problem is not the blower motor. The blower motor is actually in the engine compartment, passenger side at the firewall.
Viewed from the engine compartment, the blower motor is behind the engine on the firewall, towards the center of the car. It is usually black and has two larger wires running to it, one purple and one black.
Is it the blower motor or is it the fans in the front?if its the fans they will come on at anytime to help cool engine down better.If its the blower motor for the interior heat and air you got a electrical problem.

If it is the blower motor for your heater then it is definatly you blower resistor
Years and years and years and they quit making them because of this large problem to their new car sales. Oldsmobile had an excellent engine,
The variable rheostat for the blower motor is shot and needs to be replaced. It's on the firewall, near the heater blower, either in the engine compartment or up under the dash. Follow the wires from the blower switch and you'll find it.
No problem
Lift hood. If engine is missing, there will be a large empty space where the engine used to be.
One definition of an engine blower is a supercharger or turbocharger
The blower motor works on only one speed. The blower motor resitor pack is defective and needs to be replaced. It is located on the blower housing in the engine compartment just below the blower motor.
The horn relay on a 1991 Oldsmobile Cutlass Cierra is located on the passenger side firewall inside the engine compartment. It is just to the left of the blower motor assembly.
A blinking "check engine" light is an indication that the computer has detected a SERIOUS problem that can result in permanent damage to the engine. You need to connect a diagnostic code scanner to find out what the computer has detected.
Yes the blower is cooling the engine, the main target is to release the pressure of the engine.
usually indicates a problem in the emission control system - have vehicle scanned to determine the problem
i did have same problem on my 95 aurora i have replace ignition coils sparkplugs and wires that solve my problem
Oldsmobile never made a 3.6L engine
If the check engine light is on, use a code scanner to find out why.
