Question about 1996 Buick Regal Olympic Gold

No power to A/c Clutch

I bypassed the A/C relay and checked at the A/C Clutch connector. There is no power, but the ground is good.
According to an older schematic there should be a direct path tbewteen these two.
Any ideas?

    As there doesn't seem to be a way to respond to a message , I'll try this.


    My schematic (Buick, 1990 service manual) shows a direct path from the relay to the clutch.


    Has that changed with the 1996 model?


    And yes, the freon is low as it was pumped out in an attempt to service.

    yes this has changed,evacuate system down to 28inches of vacuum, add freon to low side then jumper the low side switch thus should turn on the compressor, keep adding freon until full hope this helps

Bypass compressor cutout relay on 01 crown vic to test a/c clutch


The relay should be a 4 pin. One terminal will have constant power and another will have power with the key on. One terminal will have a constant ground and the other will go to the AC clutch. Jump the power from one of the 2 power terminals to the AC terminal and the clutch should click/engage. Make sure you do not jump the power to the constant ground terminal

I have a 1990 Acura integra rs. I changed the fuel pump, filter, pressure regulator and main relay and it still doesn't start. It cranks but won't turnover.


Have you checked fuel pressure between tank and intake? pressure check valve on return line could be stuck open. check for spark as well, need more info....

Bypass ac relay 2000 grand am


Use a wire to connect the two openings parallel to each other just for flash. If you get a spark but no engagement then it's probably not the relay but the clutch. The clutch relies on the relay bringing the ground connections together. Find the grounds in the connector using a continuity tool or reading the diagram on the spade end of the relay, using a magnifying glass if necessary. They're hard to see.

97 chevy suburban AC clutch won't engage pressures


Looks like the low pressure switch gets power from a 10amp ac fuse. Power then goes to the ac relay which is powered on by the ac heat controller on the dash. Power then goes thru the high pressure switch to the compressor. The ac relay is grounded to the body. Do you have power on the lite and dark green wires going into the relay and is it grounded ?

No power to a/c clutch 07 infiniti


Have you actually tested for power and ground at the a/c clutch connector with a test light? If no power there, then check for power at the BK/Y wire from the high pressure cutout. RD/Y is power in, the power out goes to the cutout relay to power the clutch. If power is good to the relay, and no power out on the wire to the clutch, then the pcm is not grounding the relay. Make sure the PK/LB and R/Y wires have power in and out of the low pressure switch.------------------------------------------------------------------------------------------

AC not running in my 1998 Jeep Cherokee. Changed AC clutch compressor RELAY, freon level is good, temperature sending unit replaced along with cooling fan! Checked all fuses still good. Can't seem to...


Hello, You have two switches which work off the pressure of the Freon. Both of these switches cut off the power to the compressor. One is for HIGH pressure and the other is for LOW pressure. Check for power at the compressor clutch connector harness while the controls are set and the engine is running. You may have power and a bad clutch.

When you say that the Freon pressure is good, does that mean the pressure is within the proper range? Too much Freon will make the HIGH switch cut off power and too little will make the LOW pressure switch cut off power.

The ideal amount(ozs) of Freon is what is recommended by the Manufactuer and it will provide a moderate amount of pressure of about 35psi-40psi. You can borrow pressure gauges, called Manifold gauges to measure your system at autoparts stores with loaner programs.

The low pressure side of the system is the one you use to induce the Freon to go into an empty system. You can bypass this switch by taking off the connector and putting a "U" shaped jumper into the harness and the compressor clutch should get power to LOCK up all of the time.

You can take off the switch connector at the compressor clutch and then check for power when bypassing the HIGH pressure switch if the LOW pressure switch does not make the system get power. Only, really only bypass the HIGH pressure switch with the clutch connector disconnected. The HIGH switch is there to prevent damage to all of the components from seals to lines to every piece of Freon hardware in the car. Bypassing with the A/C clutch disconnected will allow you to know if power is getting to the compressor clutch.

Finally, you can get FREE wiring and fusebox diagrams through Autozone.com. Just sign and register to their site and then you can print the documents for yourself.

Good luck with this repair and I hope my solution helps you.

Replaced the ac compressor but now no power to compressor but have power to low and high pressure switches. checked relay under hood, relay and fuse in cabin. what am i missing?


Put a jump wire in the high pressure switch plug. If the compressor works. replace the high pressure switch. Let me know and we can go from there.

Air conditioner not working on 1993 bonnevile, compressor not engaging, charge good, power at low pressure switch, switch is closed, need to know what turns a/c relay for compressor clutch on, clutch...


the ECM supplies the ground circuit for the a/c clutch. the high pressure switch also needs to be closed to engage the clutch. when the low pressure switch and the high pressure switch are closed that completes the power circuit to trigger the relay.then the power on the #30 terminal can connect to the #87 terminal to send power to the a/c clutch.

Where is the compressor clutch relay f25O 2002


The relay is under a black plastic cover on the driver's side behind the battery. There are a couple other relays under there.-------I would start by jumping the AC relay to see if the clutch will run, you do this by removing the relay and putting a jumper wire between 30 and 87 terminals, if the clutch runs then check to see if there is power on the 85 terminal at the relay and a ground at terminal 86 if all are good replace the relay. The terminal numbers are located on the bottom of the relay, be sure that terminal 30 has power if the clutch does not run.
--
Faulty compressor clutch relay. Check to see if the relay is receiving voltage when the A/C is turned on. Also check the relay wiring and ground connections. If bypassing the relay with a jumper wire or routing battery voltage directly to the compressor clutch makes the A/C work, the relay is probably bad.

This will solve the problem or point you towards the cause of problem. Thank you for using fixya.

2005 kia spectra blower dont come on for the heater


The 2005 Spectra heating system comprises 4 main components and its associated wiring.

1. Blower Relay- supplies power to the blower motor when the key is in the on position

2. Blower motor- Located in the right side dashboard area near the passengers right foot. ( photo attached)

3. Resistor- located on the ground side of the circuit to control speeds 1 thru 3. Note" High speed bypasses this component.

4. A/C Control Module- This is the control pad in the dashboard with the blower speed controls.

The easiest way to diagnose this circuit is to split the circuit in half to determine if you have a power supply problem, ground control problem or a failed component. From your concern I am going to assume that none of the speeds work. If some of the speeds work let me know which ones and I will revise the diagnosis tree I made for you.

Key state for all tests is Key on/Engine off. Heater on and blower setting between 1 and 4.

Step 1. Verify the 30Amp blower fuse in the underhood fuse box has power and is not "Blown.

Step 2. Locate the blower motor by removing the lower kick panel on the passenger side dashboard and glove box. You will need a Phillips head screwdriver.

Step 3. Disconnect the two pin connector at the blower Connector G-02 in the attached photo. The red and blue wire is the power supply wire to the motor so with the key on/engine off check for power with a test light or volt meter. Spec: Battery Voltage. If good proceed to step 4. If no power proceed to step

Step 3.a.- the blower relay above the blower (connector G-06) and verify you have power leaving the relay. This is the red and blue wire ( Pin 4) I attached a photo of the connector to help locate the correct wire. If you have power at this pin the relay is working and you have an open between the relay and the blower motor. If you do not have power at this pin proceed to step 3.b. Verify that the relay clicks when you disconnect it from the harness and plug it back in. If it "clicks" and you have no power at pin 4 you have a bad relay. If it does not click you will need to check the power supplies to the relay. These are pins 3 (blue wire) and Pin 5 (Red wire). Be careful to check the correct blue wire as the other blue is the ground for the relay. (Pin 1). If you do not have power at either wire you have an open in the harness and further diagnosis will be needed. If you do have power at these wires then check the remaining blue wire for a ground. If you do not have a ground you may have a bad control module. To check this remove the plastic cover around the control head and radio and remove the control head from its mounting but leave plugged in to the harness. Check the white and blue wire in pin 21 of the large connector. It is located 3 pins in from the bottom left of the connector. (See attached photo). If you do not have a ground then you have a bad control module. To verify this you can ground this wire with a test light or fused wire and see if the relay "Clicks". If you do have a ground at this pin then you have an open between the relay and control head.

Step 4. - Ground check- Go to the blower motor connector and check the green and red ground wire (Pin 2) for a ground with the blower switch set to 4. This bypasses the resistor easing diagnosis. If you have a ground then the blower motor is at fault. If you do not have a ground proceed to step 5.

Step 5. Access the control head large connector. Leaving it plugged into the control head check pin 23 (Yellow black wire in the lower left corner of the connector) and verify you have a ground. If you do not have a ground you have a faulty control module. If you do have a ground you have an open between the blower motor and the control head requiring further diagnosis. simplesol907.jpgsimplesol907_0.jpgsimplesol907_1.jpgsimplesol907_2.jpgsimplesol907_3.jpg
