Question about 1991 Buick Park Avenue

1 Answer

Relay center location

Buick Park Ave 91, AC control panel is functional, blower is blowing, AC relay on the firewall isn't getting 12V at all in order to engage the AC clutch. Fuses-fusible links-breakers are fine.
Manual isn't pointing where to go for the relay center even it shows the picture of it. The dashboard AC control panel has bunch of thin wires I need to know where it goes. I am after a whiplash so I can't afford to crawl around for no reson. Thanks for the shortcut and asistance.

Finally located the AC primary small relay in the relay center under the right dashboard site. The relay had burned winding and only the resistor connected parallel to the coil was showing some resistance otherwise it wasn't engaging when I applied power to it. The Buick is actually 1990.

If it has the auto air functions.On the passenger side under glovebox remove the black cover under the dash and there is a hidden fuse block with a ac fuse. Check for this a very common issue. Also if the ac is fully charged you can unplug the low pressure switch located on the accumulator( silver canister located by the relays towards the firewall) and take a wire and place between the two terminals just make sure the compressor will does come on.If the ac is turned on and you jump that switch and the compressor does turn and ac starts working then a good possibilty that the low pressure may be bad. Would check the fuse first.

Where is the a/c relay on my Buick Park Ave Ultra. Its a 3.8 supercharged.


Hi

If your talking about the relay switch to your air conditioner. These are usually located under the hood, behind the engine and against the center rear upper firewall, in the fuse center. You have to remove the large black plastic insulator (that spans the length of the firewall), that covers the windshield wiper motor and other components, to expose the fuse center.
Pop the fuse center cover off and read the diagram inside, so you know which relay switch goes to the A/C unit.

Should you not find the relay in the engine compartment I recommend the following.

I own a 91 Park Avenue (same body style) and on many of these modules, there are additional relays behind the glove box. This is bit tricky to get to though. Because you need a Torq/star screw driver, and you will need to remove the glove comparment to get at them.

As always be sure you disconnect the negative cable from the battery before pulling any relays, to avoid shorting out your electrical system.

Good Luck.

90 buick park ave heater blower motor runs on high all the time even with key off . The heater controls don't have any effect on operation.


The switch , relay, or motor are shorted out .
First locate relay and remove it to turn the blower off.
If you want to do the diagnosis yourself ...remove the switch first and see if the motor stops. if it does you've found the culprit. If not move onto relay if the relay removal kills the motor thats good news. if it doesn't then this thing gets B+ right from the battery at HIGH SPEED. Your gonna need Shop Manual
to show you where this thing connects to the battery.
So either the switch, relay, motor , or resistors ( in your case where battery connects to the motor are your problems.
Unlessyour really good with electrical items pull the relay and bring it to a repair shop.

check to see if there is a resistor on the blower motor. it should be located either beside or underneath the blower motor.. if that is bad it wont let you select different fan speed settings and if it goes completely out the blower will not work at all.
