hi i have a w reg s type and the water heater valve work when it want's to this is a new water heater valve that i have fitted so can anyone help me so i can keep my car warm thanks

 

Shoot, Since this was in off topic, I thought you had a water heater problem at the house..

There is a Tech help section as well as a S type topic area below..

Good luck

 

And you were all ready and prepared to offer you're plumbing advice, weren't ya? [sm=icon_rofl.gif] I didn't realize you had such a sense of humor.

To the OP, as Dennis stated, your question will get let see...1000x the exposure in either the S-type section or the general tech help pages. For some reason, only a few of us diehards keep a peeper on this section (and thusly subscribe to all new posts).

 

Hi steely123.........I'm gonna move this to the tech help section where you'll get better assistance on this hopefully.

You might also remember that its considered good forum conduct to properly introduce yourself in the new member section first, usaly with a bit of a write up about you and you car before asking for help.

I'm sure that some of the tech people / S type owners will be able to offer some advice shortly.

Good luck

Jim

 

W reg would be what year? W at the beginning or end of the plate?
You put the heater valve in? Does your expansion tank look like it is low on coolant? Does one side of the car blow hot air and the other side cool? Or both cool? Does it have automatic climate control or the manual type?
When you changed the valve, did you flush the heater core?
Answer the above please for further help.

 

hi paul here in answer to your questions yes i did fit the valve and it blows cool on both sides and the w is at the start of the plate expansion tank is ok and yes the car does have auto climate control yes the core was flushed
thank you sorry to ill advice the car is a w reg yr 2000
many thanks paul from bolton

 

Just asking, are you sure you plugged the valve back in?
Is it a 3.0 or 4.0?
If you are sure it is plugged in, I will give you some wires to check if you are handy with a volt meter.

 

yes mate i have plugged the unit back in the car is a 3.0 manual

 

hi can you tell me is there a relay that run the water heater valve or is it run by the sensor on the dashboard. all the wires to the valve work ok and if i remove the valve and test it, it works this is the 3rd valve i've had cos i keep taking them back, i then fit the new 1 and it works for about 3wks then just stops. but there is still power going to it, i can fix a lot of things but this 1 has got me.
thank you for your help on this

 

Have you disconnected battery? Try 5 minute disconnect, then run climate all the way cold then back hot. I know u said you have power to valve, which wire? What are readings from all 3?
Have you checked temp of coolant hoses in and out of heater core?
Possible the sunload sensor on dash is faulty, but unlikely. Possibly climate module bad. But we will condem that last.
Also evap temp sensor faulty is possible cause. One thing at a time.
Gimme readings from the 3 wires at valve.

 

thanks will try 5 min disconnect. sorry have no meter old fashioned way 12v tester and it shows that the red wire inthe middlle of the 3 wires at the valve end to be live very bright and the other 2 wire's are live also but they are dimmer than the red 1
thanks paul

 

Ouch at test light....lol. Not good for what we need to do.

Need to know really what the voltages are. Just because the light comes on means nothing to the way the system operates.

Let us know how hard reset did. You can get a cheap meter for about $5.00. Don't know what they cost over there, but I am sure they are cheap too.

 

hi did the disconnect for 5 mins it did nothing i'll see if i can get a meter of someone and them we can test the wire's
thanks

 

hi with my tester i tested the wire's on the valve if i remove the plug only the red wire works if i connect the plug all 3 wire's work i get the feeling that the valve is not being told to open or close co's i got my hands on another valve and connected the plug to it with the car running and nothing happened but if i get 2 wire's from the battery and touch them to the valve 's connection's the valve opens and closes

 

hi jag man
i have a meter pls tell me what to set it to and how you want me to check the wiring
thanks

 

Ok, put it on Volts DC. Ground the black lead and put red lead to center wire, should be red. With vehicle running you should have 12 Volts there. Next put red lead on Brown/Green wire. This is for drivers side. You should have 12 Volts at low temperature and 0volts at high temperature. Next the Brown/Blue for passenger side. You should have same thing. 12 Volts at low temperature, 0 volts at high temperature.
This is of course with the valve plugged in. Back probe the wires with something smaller than say a paper clip and make sure you have good connection. This will be easy on the first wire as 12 Volts you will see if you are doing it correctly.
Let me know results.

 

hi ok done the test as you have told me to and the reading i got was 13.74v with the heating in at it's highest and at it's lowest
thank paul

 

In that case, do you know how to remove the audio and climate stack?
Pull the very bottom cover out from below the radio. Pull the two side pieces from the bottom that are beside the climate panel. Now you have 4 8mm bolts exposed. Remove them and pull climate/audio unit forward. I need to look at diagram for the right pins. Use the meter back there to make sure voltage is changing. If it is not, then you need new climate control panel.
I will repost shortly with pins. This is colour specific also (the panel), you may be able to find one used from a wrecking yard. I think will need to be programmed. I cant remember.

 

hi
yes no prob i have removed the audio unit
thanks paul

 

VIN CAT specific part..
