Solution: A common issue in 1999 models of the Ka, the problem is a poor electrical contact that's on the blower motor resistor multiplug. The result is a high electrical current, and that's melting the multiplug. You'll need a new blower motor resistor from our store, as well as a new wiring loom. May 2, 2019 · 2011-16 Ford f series ac fix bad evaporator temperature sensor instead of pulling out the dash which is about 10 hours book time to actually replace the sen Sep 13, 2019 · Adding coolant to a radiator dry enough not to trigger the engine temp sensor can cause problems from drastic temperature change. Let it cool down first. Fan Clutch. Like any other clutch, a fan clutch will wear out over time. If everything else seems on the up and up, the springs in the fan clutch have worn past the point of proper function Sep 29, 2023 · The AAT sensor is a two-wire sensor with a negative temperature coefficient resistor positioned so that it reads the outside air temperature. One of the two AAT wires receives about 4.6 volts from the ECM/PCM, Instrument Cluster, Body Computer, etc. and the other wire is a reference ground, also from the module the sensor reports to. Sep 2, 2010 · I've encountered a problem with my 2008 Focus, where my dash display makes the temperature -60c! The problem has occurred after disconnecting the negative terminal from the battery to replace a standard 6000 CD Radio with a Sony 6CD Changer unit I bought off eBay. I had The battery disconnected for about half an hour, whilst I done this. Jun 13, 2017 · Some 2014-2016 Transit Connect vehicles equipped with 2.5L engine may exhibit an intermittent condition in which the ambient air temperature (AAT) display in the instrument panel cluster (IPC) is inaccurate and/or the A/C is inoperative. The inoperative A/C may be caused by the AAT reading below -1.1 °C (30 °F) the actual ambient temperature Apr 26, 2016 · If IAT2 is reading properly, suspect an intermittent sensor or harness problem, possibly an ECM problem. If IAT2 reads something unusual, -30 °F or 300 °F, suspect a sensor or circuit problem. Disconnect IAT2. If the reading doesn’t change, suspect a circuit problem. If the reading changes, suspect a sensor problem. Repair or replace as Oct 4, 2021 · 5 posts · Joined 2013. #1 · Oct 4, 2021. The ambient air temp sensor on my 2012 Focus SEL has been wonky for a couple of years now and reads much higher than it should. I've never given it much thought (I've had a LOT of problems with the car, gotta pick my battles!) until recently when I've noticed the car possibly thinking the engine temp May 2, 2011 · Ford Year: 2019.
