Pin 85 or 86 can have power with key on. and pin s 30 should have power all the time. If 85 or 86 has no power then check the fuse. No power to the fuse? then it is time to do some wire chasing, maybe. Year make and model helps.Some panels have computers built in.

The compressor is not powered or the fuse for the clutch unless the system has a minimum pressure, so if you are low on AC refrigerant or the low pressure switch is defective then the compressor will not engage, 99% of the time one of these is the problem.

Diagram for a/c control board 99 tahoe compressor not engaging

Is the system full of refrigerant ? Low pressure cut out switch could keep the compressor from engaging > The PCM/ECM -engine computer controls the engagement of the compressor clutch. Rather then jumping the relay, test for power an control . If you pull the relay out of the fuse box an look on the bottom of the relay , you will see 4 sets on numbers 30 & 87 - 85 & 86 . you proved 30 has battery voltage by jumping it to 87 , now you need to check the control side of the relay . Pin 86 should have battery voltage while pin 85 supplies a ground through the PCM/ECM .

I have a 2007 jeep grand cherokee that the cooling fan wont come on, I replaced the fan relays,temperature sensor and cooling fan .

Did you check the fuse and the voltage at the supply side of the relays? How about the wiring and particularly the connectors? Also, it is not unusual for a new temperature sensor to be faulty - try jumping the contacts in the sensor connector to see if the fans activate.

2001 Chevy blazer came out one day and it was dinging as if my key was in it got it to start with a jump shut it off took battery out and charged it put it back in when I turn the key I get NOTHING!

Check power an grounds for ignition switch , voltage drop test the starter circuit . Go to youtube an check out videos on basic electrical trouble shooting , voltage drop testing ,how to read a wiring diagram .Then go here http://www.bbbind.com/free_tsb.html free wiring diagram ! Look at power distribution under electrical distribution . Check main fuse's Maxi fuse's that power the ignition switch ,IGN.C fuse 20amp in underhood fuse box ,then check crank fuse 10amp in same fuse box .Check the starter relay in the under hood fuse box . Check the circuit form ignition switch to the starter relay , pull the relay out an look on the bottom you should see 4 set's of numbers 30 - 87 - 85 - 86 . Pin 30 or 87 should have battery voltage ,one or the other ,not both . if you jump those two at the base (where it plugs in ) not the relay pins . It should crank the engine ( if starter is good an there are no opens in the circuit ) Pin's 85 an 86 are the control side of the relay ! You may want to check out videos on how a relay works also > Good luck hope this helps

2005 Lincoln Aviator the cooling fan troubleshooting it

There is a cooling fan relay in the under hood fuse / relay box . There is a fuse F1.8 20amp in the same under hood fuse / relay box ! If you pull the relay out of it's socket an look on the bottom you'll see some numbers , 30,87,85,86 ! 85an 86 are the control side of the relay an 30 an 87 or the load -fan side ! If you take a test light or volt meter you can check for battery voltage at pin 30 ,you could take a jumper wire from pin 30 to 87 an the fan should run , if the fan motor is good an there is battery voltage at pin 30 ! Pins 85 an 86 are the control side of the relay ,pin 86 should have battery voltage an pin 85 is from the engine computer ,when the temperature get's to 195 - 213 degrees the engine computer will ground pin 85 through a transistor inside the computer energizing the relay turning on the cooling fan ! You can test right there at the relay ! VEHICLE RELAYS Operation Diagnosis

2004. Why is the blower motor not receiving power?

The blower motor relay in the auxiliary junction box under the hood is good ? All relays ? only one controls the blower motor ! The electronic automatic temperature control module turns it on by supplying a ground inside the module ! The 30 amp fuse for the blower motor is located in the under hood auxiliary junction box ! At the relay socket test for battery voltage at pins 30 an 86 ,power form 30amp fuse ! The other two pins 85 an 87 ,85 is circuit to the electronic temperature control module . You could test this part of the circuit too , with a test light or volt meter . But if no voltage to the blower motor ,could be the electronic temperature control module is bad !

The a/c compressor clutch will not engage even when I jump the low pressure switch thats mounted on the top of the accumulator (dryer). Is there another method such as direct from the battery? There are...

The low pressure switch is just a sense input to the PCM - powertrain control module > Grantit , it is needed for the PCM to know the pressure in the system . But the PCM must energize the compressor clutch relay for the compressor to engage . Finding the compressor clutch relay in the under hood fuse / relay box an testing there would be the best place to start . Pull the relay out of the fuse box , look on the bottom ! You should see four set's of number's ,30 & 87 plus 85 & 86 . 30 & 86 should have B+ voltage . Use a multi-meter to test . 85 goes to pin # 1 connector 3 at the PCM . The PCM supply's a ground here to energize the relay if condition's are right . You could jump pin's 30 & 87 an if the compressor clutch coil is good ,the compressor clutch will engage . Video's on youtube showing how to do these test .

When i bolt the ground wire to engine behind alt, the ac compressor clutch locks on and stays on with key on or off. any suggestions???

The only thing it could be is the conrtol wire of the A/C compressor clutch relay is shorted to one of the wires grounding at the alternator . The PCM - engine computer controls the grounding for the A/C compressor clutch relay. Find the A/C compressor clutch relay in the under hood fuse box , pull the relay out of the fuse box an look on the bottom . You will see four sets of numbers . 30 & 87 plus 85 & 86 . Take an ohm meter an check pin 85 to ground with the ground wire's behide the alternator connected , you will have continuity . Disconnect the ground behind the alternator an you will probably have a open circuit . When the motor was changed wire's were pinched or something . Most likely . Here , check out the wiring diagram http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model an engine size . Under system click on HVAC , then under subsystem click on HVAC controls . Click the search button ,then the blue link . Fourth diagram down is for the A/C compressor clutch relay circuit. Don't know if know how a computer controlled relay circuit work's . Looking at the diagram .The DB/OR - dark blue with orange trace wire would have to be shorted to one of those ground wire's for the compressor clutch to stay engaged .

98 mercury trace no 12 v going to the ac compressor

check your fuse box for a blown ac fuse, fuse box usually under dash, sometime under the hood of the car usually on drivers side. bad switch?
check if you hot wire lead might be pinched and grounded out or broken wire between battery and switch

Is there a resistor or relay switch that sends power to start compressor

There is probably an a/c clutch relay in the fuse and relay box. The most common reason for the a/c clutch not engaging is a low charge though. Have you hooked gauges up?

Air Conditioning

If you have no power (12v) to the power wire at the A/C compressor clutch and have jumpered all of the switches then you need to check for power coming out of the A/C switch on the dash. Also there might be a pressure switch on the back of the compressor that you can jumper also. You can also check A/C compressor relay in the under hood fuse/relay box. There might be a fuse in the under hood fuse/relay box for the A/C too. Hope this helps.
