Howdy,
If your AC system is low on Freon, the system goes into a no run mode. If you disconnect your battery for a few minuets the computer resets itself. Then the Freon level can be checked by a friendly shop. Might find it low. Good Luck!!!!!!!!!!!!!!

1992 Buick Park Ave. Ultra TPS problem


The code indicates the TPS is still bad and the code is usually right, but it could be a wiring issue at the TPS connector or less likely a computer issue.
To test the TPS circuit, you need to check voltage and ground from the ECM - 5v is the normal reading between the ECM reference circuit and the ECM ground circuit at the TPS connector. Checking the TPS signal circuit to the ECM requires monitoring the TPS signal on a scan tool while jumping the 5v reference and the signal circuits. The TPS reading should go from high when the circuit is jumpered to low when the jumper is removed.

You should make sure you have proper charge for sure.has your battery gone dead lately? I know on some of them digital climate controls will act exactly like this and have to be reset or go through a setup sequence.

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.

Behind the glove box you will see the heater box. On top of the heater box you will see a set of wires going to a small controller box that has an arm on it. It is probably not working and you can only by them at the dealer. It is the dual climate controller and cost approx. $100.
