1995 Lt1 Camaro cooling fans operate like this; Cooling fans (2 fans) come on 30 seconds after start up on high, stay on while driving, and turn off when brakes are applied. Stock car, no mods.


Did you have it checked for DTC'S - diagnostic trouble codes ? The cooling fans are controlled by the PCM - engine computer , with the use of three relays ,located in the under hood electrical center . Do you know how to do electrical testing ?

What is a check engine light code PO480?


I'm quite sure it is a low speed fan control relay circuit malfunction. I'm not sure that driving would cause problems aside from fan not working. Hope this helps.

Fan will not run when hot


Check fan relay. Remove passenger headlight, cut plastic to find relay. Replaced mine last night. Radiator fan spinning again. Was having temp spikes at start up and idling. Also bought coolant temp sensor but have not installed. Before I replaced fan relay, check engine light wasn't on. Now that the new relay is installed, light came on. Autozone and Discount Auto have an OBDII sensor you can borrow for free to read the codes stored on computer. Codes are generally stored when the check engine light comes on. Getting minr checked today. Will update solution later if needed. Relay was $55.

COOLING FAN WONT KICK ON. DID A JUMP TO THE BATTERY FROM THE OUTSIDE PLUG AND FAN KICKED ON. BOUGHT A NEW RELAY FOR UNDER THE DASH BUT FAN STILL WONT COME ON. IS THERE A FUSE TO?


The cooling fan relay is located in the engine compartment just behing the left headlamp...not under the dash. There are cooling fan test connectors built into the wiring harness near the left strut tower. The cooling fan relay is controlled by the cooling fan temperature switch located on the rear of the engine. There are 3 temperature sending units on your car if it is equipped with a temperature gauge. If not, there are 2 sending units, One is for the computer and the other is for the fan relay.

The one for the cooling fan will have 2 wires, one Tan and Orange and the other Brown and White.

The cooling fans and cooling fan relay get their power from fusible links built into the wiring harness near the starter relay.

Fan relay is located under pass headlight. Remove light assembly, use 2 1/2 " hole saw to drill hole in plastic housing ,3"from back wall, 3'' from left side.This will put you right over relay. Unscrew two bolts,replace. Relay was $40.... dealer wanted$350 to remove front bumper to replace it.

Code p1652 on a 1996 pontiac grand prix does anyone know what it means the book for computer codes is incomplete


Trouble code P1652 means: Cooling Fan 2 Relay Control Circuit Malfunction

I would start by checking power supply to the cooling fans,making sure the coolant system is full,& using a scn tool to verify the proper operation of the cooling fan system.Here is some info to help you.

The Powertrain Control Module (PCM) controls the operation of the cooling fans. This is accomplished by providing a ground path for the cooling fan relay coils within the PCM. The relay contacts will close and complete the circuit between the fusible link at the battery junction block and the fan motors. Whenever there is a fan ON request both fans will be running.

Power for the fan motors is supplied through a fusible link at the battery junction block. Battery positive voltage is applied to the cooling fan relay contacts and coils. The cooling fan relays are energized when current flows through the relay coils to ground at the PCM. The cooling fan relay #1 control circuit is used for low speed cooling fan operation. The cooling fan relay #1 control circuit and the cooling fan relay #2 and #3 control circuit are both grounded for high speed fan operation. The cooling fan relay control circuits are monitored by the PCM. Before using the Electric Cooling Fans diagnostic tables be sure to perform the Powertrain On-Board Diagnostic System Check. If diagnostic trouble codes P1651 or P1652 are present, use the appropriate DTC diagnostic tables prior to performing Electric Cooling Fans diagnostics.

Important:
When certain Diagnostic Trouble Codes (DTCs) are present, the PCM may command the cooling fans to run all the time. It is important to perform the Powertrain On-Board Diagnostic System check prior to diagnosing the engine cooling fans.The PCM will complete the ground path for cooling fan relay #1 under any of the following conditions:
- When engine coolant temperature exceeds 105°C (221°F)
- When A/C is requested and ambient temperature is greater than 10°C (50°F)
- When A/C refrigerant pressure is greater than 190 psi (2 volts)

For high speed cooling fans operation, the PCM will delay control of the cooling fan #2 and #3 relays for 6 seconds. The 6 second delay ensures that the cooling fan electrical load will not exceed the capacity of the system. The PCM will complete the ground paths for cooling fan relays #1, #2, and #3 under any of the following conditions:
- When engine coolant temperature exceeds 113°C (235°F)
- When A/C refrigerant pressure is greater than 275 psi (2.9 volts)

If a problem that involves the low speed cooling fan relay control circuit (cooling fan relay #1 control) exists, DTC P1651 should set. If the problem affects the high speed cooling fan relay control circuit (cooling fan relay #2 and #3 control), DTC P1652 should set. A problem with the ECT sensor should set DTC P0117, P0118, P1114, or P1115. Any of these DTCs will affect cooling fan operation and should be diagnosed before using the Electric Cooling Fan Diagnosis table. The Electric Cooling Fan Diagnosis table should be used to diagnose the PCM controlled cooling fans only if no DTC is set.
Hope this help to solve your poblem (remember rated and comment this help).

My fans that cool the engine do not come on. The car seem to cool down when driving but the temperature goes up when I am sitting still. The check engine light is on steady.


Hi!

The first thing you're going to want to do is get that trouble code read. Some auto parts stores do it for free or you can buy a code scanner. Likely culprit is going to be the cooling fan itself, the relay, fuse, or the wiring/connectors leading to/from the fan and PCM. It could also be caused by a failed coolant temperature sensor.

So get that code read and start some diagnostics. I would suggest you start by checking fuses, relay, wiring. Then use a digital volt meter to see if the fan is getting 12 volts. Then try hooking the fans up directly to the battery to see if they work.

If you need more help, just let me know. Good luck!
