Pre-Serp car...Have looked over the entire front end from under the car and can't find the thermistor. Can someone tell me where it's normally located or post a pic of what it looks like & location? A prior post on Pistonheads said the wires were orange or orange/white. My dash light has been solid red for a year and I already bought the replacement thermistor diode, but need to locate the original to replace it.

It will be a simple 2 pin connector probably just laying down in the bodywork ahead of the rad or possibly round more towards the left wing which is where the loom comes down from the footwell.

When you find it you will be confused because both parts of the connector will be there but there will be no wires coming out of one side. Unplug the connector and bring the loose half to the bench. On closer inspection you may see where the thermistor was originally crimped into the terminals but has corroded away and is now missing.
Originally the thermistor had a small length of sleeving over it then the legs crimped into the terminals. When complete the thermistor sat almost hard up against the end of the connector body.

As you say the wire colours are Orange and orange/white.

In my 94 SERP it was lying in the void space under the nearside headlight.

Can I butt in here as I have an interest in this thread, not that I'm bovered 'cause I don't go out in the cold.

Anyway here is a photo of the centre facia on my '92 Griffith.



Would my car even have an ICE warning and if so could it be the Mystery light in the photo which doesn't do anything unlike all the other lamps on the car?

cool

Is the mystery light on my car the usual place for the ICE indicator?
I can't find any info' from the Bible or Owners manul as to where it should be located if it was fitted with the function originally.

cool

Hi Dave

Please can you post a photo of your ICE thermistor plug in your 94 serp Griff. I also have a 94 serp with the dreaded red light continuously on, I have bought a new thermistor but I cant see the connector.

Thanks
Gordon

I too would really appreciate a pic of the ICE Thermistor location on a 94 Griff. I've looked the entire Front end over and cannot find it's location or any related orange/white wiring. I've also got the headlight pods out (replacing the original low beam lamps with Hella projector beam lamps ), so was hoping to see the ICE Thermistor located under them, but no luck with both pods out. A pic of the thermistor or wiring location would help me trace down where it's located as I've had no luck locating it! Thxs in advance for a pic or two!

This is mine on a 97 Chim. The loom comes down the nearside wing and across the front of the radiator. The thermistor in on a branch from the loom about the centre of the grill. Just behind the number plate is as far as it will reach.

Thxs Soooo much Steve! Going on another seek & find mission later today now that I know what it looks like. Also, THXS for taking the time to take pics and especially taking the connector apart so I can see what it's "supposed" to look like and how the thermistor is installed!
Thxs Again!

Thanks again Steve. I think the whole thing is completely missing in mine. I will have another look but I think the wires have just been cut off.

Interesting, I've had my Griff from new so it's 21 years old. The ice warning light worked for about a year but then went red. I just ignore it but I suppose it would be nice to fix it. Where do you buy the replacement thermistors?

I think I can safely say the mystery non-working light on my centre facia in the photo I posted above is in fact the ICE warning indicator.

Being the only thing not doing it's job I should investigate getting it working.

Here is just one of the threads on the subject.

No Lance, pre-cats did not have ice detectors. The light you refer to is the original factory fit alarm light. On mine it flashes green when the car is locked, although in the book it says it should flash red when the car is locked.

That alarm button and light on above it in your photograph was not factory fit. It is therefore likely that your mystery light no longer does anything if the original alarm system either isn't working or has been removed.

The car which was subject of that other thread you linked (I only read the first post, not the whole thing) was a 500 and had a different dashboard and switch layout to the pre-cats.

Many thanks Duncan,

Saved me a job then.

But I did do a search for the thermistor and decided the exorbitant, P&P shops wanted, probably their minimum, put me off the idea anyway.

Ice detectors were available as an Optional Extra for 4.x pre-cat and V8S models, at a cost of £70 (Inc VAT)!!! With this option there was a second LED indicator mounted just below the alarm armed indicator.* The thermistor was mounted in the lower front nearside area in the vicinity of the fan blower inlet grill.

(*In fact just to the left, see pic. The ice detector LED was labelled as well.)

My first pre-cat had an ice detector and heated seats, both worked well, a Winter Package option if you like.

Reminds me of a post I put up 20 odd years ago:

With the coming of Santa Klaus and the white stuff, I thought to myself wouldn't heated seats and a nice warm backside make driving and travelling in the Griff a tad more pleasant. Especially with the top off!

Surprise, surprise, on checking both seats I discovered electrical cables running into the rear of them. Can only be heater elements I told myself, but how to switch them on, that was the problem. I remembered a recent post regarding the same problem with a Chimaera, so I searched high and low in the vicinity of the steering column, but there was no separate switch to be found.

Then whilst playing with the fan speed switch, hey presto it has a pull-out position (probably for a redundant HRW option), and yes the seats began to warm up. Great. True to form there is nothing in the Griff's Owner Handbook concerning this option (or the Ice Detector).

I stand corrected Dave. Always something new to learn about a pre cat.
