How do you get the stock radio deck out of a 1991 buick park avenue?


*It's a bit tricky but not difficult, if you know how the dash in the Park Avenue is put together. But before you do anything, safety first. *Disconnect the negative cable from the battery before doing any electrical work on a car. This prevents shorting out your cars electrical system.

*If you own the 90 -91 Park Avenue model, simply pull off the decorative trim away from the radio to expose the torq screws that hold the radio into the dash. You will need a torq screwdriver of the right size to remove the radio.
Available from your local autoparts store.

*If you own the 91-92 model, it's a whole different ball game. This since the dash is much more tightly compacted. It's a combination of a snap together assembly and Torq screws. The dash is held together in columns or sections.

*The torq screws on these models are hidden behind the heater vents in the upper dash. First pry the wooden trim (Which surrounds the climate control module) on the bottom of the dash off, gently but firmly until it comes free, exposing the Torq screws on the lower dash. Remove the heater vents (hiding the upper screws ) by popping them out with a straight blade screw driver. Then remove all Torq screws visible to the eye, only from the column that is holding is holding the radio in place.

*You will then be able to remove the black colored plastic off the dash to expose the radio. (Use care when removing the lower dash column as some climate control and airbag sensors might be embedded).

*Remove all Torq screws holding the radio in place, (and keep track of all screws) pull the radio out of the dash, and disconnect electrical connectors. If you'll be replacing the stock radio with a non factory radio, make sure all electrical connection watch up, since security feature in the radio are integrated into the radio. (some of these effect basic function on your vehicle like the headlights) If you will be reinstalling the stock radio, you will have to have it unlocked by the dealership. The DelcoLoc system will now think the radio is stolen, because of it's internal security features. Installation is the reverse of removal.

Hope this helps.

1995 Buick Climate Controls Going Crazy


Same thing happened with my 95 park avenue a few weeks ago. I talked to a guy I know who is a GM mechanic and he says that the module (the thing on the dash with all the buttons and the temperature display) is broken and needed to be replaced. These computer modules just get funny with age and eventually have to be replaced. You can find one pretty easy on ebay motors. It's not hard to replace, you just have to take apart the dash and take out the old module and put the new one in. Hope this helps!

1991 Buick Park Ave. climate control stopped working. Replaced electronic (dual zone) climate control module, unhooked negative battery cable to reset module and climate control worked for appx. 3 weeks,...


Check to make sure that you have enought freon to engage the compressor, then you will need a flow chart to take you through the rest of the steps necessary to diagnos this problem. The Electrical system manual for Buick is the only one that will have the proper information for you to walk through the steps to dead head it. There is a HVAC programer that is behind the floor heater duck work. It has a numbering system that goes from (2) rows of pins that go 1-16 for terminals.On terminal 5-7 with ignition in run position, you need bat. votage. Terminal 10 & 11 you need 4-5 volts. Neither 10 or 11 should be unplugged just yet since 10 feeds 11 pin. If there isn't any voltage at these pins, check for corrosion on the pins theirself, or for the pin that it may have slipped back out of the connector. Good luck.
