Try the paper clip in the sensor lead to see if it comes on then. Quote

nicebutdim Posted December 2, 2011 Report Posted December 2, 2011 On the wiper linkage, under the scuttle plate, is the temp sender. carefully remove the plug and bridge the contacts in the plug. 4c is nowhere near low enough to trigger the aux heater, it really needs to be in the minus numbers. Another test is to put a bag of frozen peas on the sensor, leave for a few mins and then try. Quote

nicebutdim Posted December 2, 2011 Report Posted December 2, 2011 What year is your Gal? I have a mk1, which the cover is removed by 3 bolts, one in the middle and one each end and then carefully pulled out towards the drivers side. Have a look through some of the threads here if yours is different. You need to just make access to the linkage for the wipers, you 'should' see the sensor clipped to the linkage. Quote
nicebutdim Posted December 2, 2011 Report Posted December 2, 2011 Its a mk1 Open up the bonnet, you'll see the long black plastic panel above the engine. In the middle is a bolt (10mm head) that faces towards you. There is a bolt at each end (10mm too) that almost faces the wiper arm spindles. Carefully pull the wiring loom from the plastic panel on the passenger side, the loom goes into the bonnet itself. Pull the panel towards the front of the car, and then you'll need to manipulate it over the header tank by pulling towards the drivers side of the car. You should be able to see the mechanism of the wipers. On one of the arms there should a clipped on sensor. After you have finished testing be careful with how you put the panel back, with the cable on the passenger side and with the plate location. There is a locating lug on the rear of the panel, ensure it clips into it's clip on the bulkhead before bolting the panel back in. To be honest with you, I really don't think it was cold enough this morning to trigger. It really does have to be brass monkies and although it's been quite cold, it hasn't been really cold (yet) lol. P.s. are you having trouble posting replies? Quote
