Tis-2000 says to first check fuses FV8 (40amps) and F42 (5 amps).
Without Airco only relay K30A is used.
With Airco relais K30A, K30B and K30D are used as well as resistor block R8.

Thanks for quick response oldford,but could you let me know where these fuses and relays are situated?There are 6 big fuses in a box under the plastic skuttle panel on N/S behind battery and under wiper assy.I can see what might be a fuse box right at the basck ,the top ios held down with torx screws.Is this the fuse/relay box?Rob

I have now removed wipers and plastic skuttle panel and top off box behind battery.Its full of relays,3 large yellow,2 lge purple,a line of 5 smaller black ones,4 smaller grey,1 small black,a double lge yellow {flashers} and 2 lge browns.The 6 large fuses are ok and all the fuses in the fuse box in car N/S end of dash.Does anyone know which relay is which and is the resistor the part plugged into the radiator fan housing?Rob

What scanner are you using Rob?
What is the actual fault?
Why do you think it needs a relay replacing?
What resistor are you looking for, and why?
Could the part plugged into the radiator housing be the fan control module?
What about wiring checks?

Maybe employing a good diagnostic technician could pay dividends [try the good garages link].

It brings up fault code P1482 indicating a fault on the high speed fan relay/circuit.using our solus,we can activate the low speed and high speed fan,the low works,the high doesnot.We have identified the fan relays as being the brown ones in the relay box,when swapped over,the low speed still works and not the high so relay is OK.Both the relays click when activated with solus.The low speed relay has a live feed to the 30 terminal on the relay and the high speed has an earth connection to the 30 terminal.Is this right?Rob

a couple of questions has some one been buggering about with the bcm settings (ie whats it previous history) second question is do's it have a resistor sitting in the rad motor cowling if yes then there are three relays K30a K30 b k30d, if answer no to resistor then the vehicle only has 1 speed (in which case someones been playing with it !!!!)

K30 a and b are in the relay box behind battery k30 d is in the row of relays in front of battery clipped to scuttle panel just under flip lid cant see where pin 30 on relay is getting its earth (you dont mention which relay, a or b ((left relay or right relay))), only earths are supplied by ecu and other side of motor, Regards TB

 

ps sorry oldford for going over same ground

i have known this to be a 30A green maxi fuse in the engine compartment fuse box on a corsa D(is it the same as a meriva? im not too hot on vauxhall models).

the customer blamed me for creating the problem though because the managment light was not on until i serviced it, i only popped on launch to do a fault code test like i usually do on every service i carry out(would have used ethos on EOBD but it was the spanner light which brings no fault codes under obd protocol). i was glad to find a £1 fuse to keep the customer happy.

if you are unsure of which fuse, with the ignition on use a power probe to detect if there is a feed to each fuse on both sides of the metal bits on the top of the fuse, this test is not foolproof but can find a fuse quickly without looking up the fuses on the computer or in the handbook.

Would rather be playing pool.

Hi,

I'd try little refresh as I am having same code 1482 and issue with 2nd speed (I think) of cooler fan as at about 90 degrees control light come up on dashboard. Some times it flash (not so quicklly) and disappear and than come up again or it just lihgt up for longer periode. I checked resistor so far but wonder what was the fix in case opened here.

On which pin of which relay to check supply for both speeds? Do you have any schema to find out how it works?

Thanks

Martin

hi just wanting to know if you sorted your problem , cos i am having the same problem , code p1482 , the cooling fan is working but when the 2nd speed for the fan about 90degrees , kicks in, after 5secs the relay knocks off , dont know really what to check for or change or were to look , my guess could be a faulty wire but dont know . if i am right ,the fan on speed one runs on a 8volts then 2nd fan bumps up to 12 volts ?? so maybe the voltage push is tripping relay ?? thanks for any help andy
