So the control module needs replacing, im having same problem. Was told control module is good when both fans run, so is it the control module? All fuses are good?

What is the max. temp. for 2004 4x4 trailblazer


Depends.
A normal cooling system runs between 195 degrees when the thermostat opens, to 230 degrees when the cooling fan kicks on.
If you are experiencing air temps over 90 degrees, the cooling system could run at 210 or higher.
Idling and moving make a difference too.

Vw jetta iv, temperature alarm sounds and flash with no aparent reason. temperature dial indiator is ok.


I WOULD CHECK BOTH RADIATOR HOSES TO MAKE SURE THEY ARE HOT. THERMOSTAT COULD BE STICKING SLIGHTLY CLOSED.CHECK COOLANT LEVEL MAKE SURE COOLANT NOT LOW.IF COOLING NOT BOILING OUT OF THE EXPANSION TANK. I WOULD HAVE CAR HOOKED UP TO A DIAGNOTIC SCANNER AND CHECK COOLANT TEMPERATURE SEE IF TEMP. OVER 230 DEGREES IF SO RADIATOR COOLING FANS NOT WORKING.COOLANT THERMO SWITCH BAD BOTH FANS SHOULD BE RUNNING AT LOW SPEED.IF ALL LOOKS GOOD YOU COULD HAVE FAULTY LOW COOLANT SENSOR IN EXPANSION TANK.MAKE SURE COOLANT IS IN THE EXPANSION TANK BECAUSE COOLANT LEVEL COULD BE LOW.ADD COOLANT IN THE EXPANSION TANK UNTIL YOU AT MAX LEVEL LINE ON THE EXPANSION TANK.DONT OVER FILL THE EXPANSION KEEP ADDING COOLANT UNTIL COOLANT LEVEL STAYS AT THE MAX LEVEL LINE ON THE EXPANSION TANK.

sounds like you got stuck pretty good,.....could have knocked a wire off the cooling fan, or punctured something to make a leak of the coolant,...check coolant level, let it run and see if fan comes on as the temp is increasing,.....good luck, cracklin joe

Locate your rad fan relay, and next time it does it, give it a quick rap with handle of screwdriver or similar weapon. If it stops, replace relay.

2004 Jetta GLS. Main cooling fan remains on after car turned off.


"Already had replaced: both cooling fans, fan control module, coolant temp sensor, fan switch, 4 terminal connectors. No trouble codes reported in VW electronic diagnostic test. 2 different VW dealers and and my mechanic threw in the towel. Any suggestions greatly appreciated."

This is a common problem with the VW..and no one has an answer WHY. (including VW mechanics)

THIS IS A RECALL ISSUE and should be implemented

Jetta 2003 2l fault code p2182


P2181 Cooling system performance

Check Thermostat operation & Temp sensor for ECU. CHECK ENGINE CCOLANT TEMP SENSOR IN WATERHOSE, NORMALY A 4 PIN PLUG. ON SENSOR SELF PIN 1&3 OR C&D AT 0 degrees
5000-6500 ohms,60 degrees 530-675 ohms,90 degrees
200-275 degrees

Could also be the cooling fans - I've heard of fixing it by replacing the fan motor and clearing the code as well. The easy fix seems to be the coolant sensor though - I've seen several online threads where owners cleared this code by changing that sensor.

2002 VW fan stays on too long?


How does the temperature gauge read on your dash.. Is your car temp at 190 degrees while driving.. If its higher than 190 your overheating and that would cause the fan to cool her down.. good Luck
