Removing the capacitor is just a matter of disconnecting a few screws and wires. Another JR. - Barry4085. Circuit boards are more likely to fail on their own. I've checked the fuses under the hood and in the central junction box but all related fuses are in good shape. Most homeowners in need of new heating or cooling equipment will do an internet search to get information. If you let the battery run low the car might be in Transport mode. 5A) with the ignition switch to the ON position. Climate control not working. It turns out that the passenger side solenoid coil was shorting out. Thermostat not switched on. Such a search will typically yield two results: what to buy or where to buy but not why to buy. 04-28-2010 07:17 PM. Power from the thermostat goes back to the circuit board and onto the furnace, fan and outside AC unit. I've checked all fuses in the panel on the drivers side of the car, anywhere else I can look to see why there is no power going to that stuff? 14. aznewsh, do the idiot checks first.
If you pull the main plug with several wires going into the board you may discover a burned socket in the plug, another indication that the board blew out. Another cause for the AC not working is low pressure. Once you have removed the thermostat from the wall, you will need to use a screwdriver to remove the battery cover. QUOTE=vlogozio;4569948]Thanks Dan, I have attached a pic of my climate control. Also when I try to push the A/C, circulation, or heated mirrors button nothing happens. A failed capacitor is a pretty common reason for the AC not working. Climate control no power. I will also note that the radio still works, and all of the lock/unlock and window controls all work as well. Granted, having the fans stay on after the car is turned off and the other problems you mention make it sound more like a bad A/C module. Additionally, when there is an airflow problem, it can cause the furnace or AC to overheat or freeze.
When air is blocked from circulating through the heating or cooling process, the HVAC system can not keep up, and thus the thermostat will not satisfy the desired set temperature. You will have to very carefully take note of how the wires are connected. I check all the fuses and I cant seem to find one that even serves the function of the climate control. Lost power to air climate control unit. 30, move on to next step. We mentioned before about the circuit breakers or fuses at the main electrical panel which you should have already checked and reset. But before you start calling around for thermostat repair or a new thermostat installation, there are a few things you can try. No power to climate control panel for 2012 glk 350. A dirty filter, blocked or closed vents, and a dirty HVAC system can inhibit airflow, directly showing up on the thermostat. Join Date: Nov 2022. A fuse looks like a glass tube with metal pieces on the end. The 200 is to check voltage between 0 and 200, so use that setting when checking for 24 volts. If your thermostat is not working, ensure your furnace switch is on, and your HVAC circuit breaker is correctly set. Hey there, I got a 1996 Dodge Ram with 5.
What could be stopping power to the other 6 wires? They seem to cost about $70 ($60-85), and then there are a bunch on eBay for $20. As a thermo stat helps you and your family stay comfortable all year long, taking care of any device issues should be a top priority. 10-29-2005 02:36 AM. Next possible cause of the AC not working is something is not connected. Azn = check under hood fuses f6 & f8. Climate control module has no lights or power. I took the Climate Control Unit out (by largely following the Pelicanparts tutorial for W204, with some modification since mine is X204) and used a multimeter to test the electronics with a new fuse (without starting the car). Many do not realize that thermostats can be compatible with multiple types of equipment. No defrost, ac, heat or anything. To diagnose this, remove the thermostat's cover and search for a fuse. The first possible cause of your AC not working could be at the breaker panel.
The Ohms test will tell if the capacitor is at least not completely shot. No power to climate control panel on climate. A bad solder joint is usually the original problem on these C5s. Your thermostat and HVAC system will function at its best when you need it most if it is maintained in top condition. Some meters will have 2 AC settings, for example a 200 setting and a 750 (AC for alternating current, not air conditioning). Then you can remove the panel on the condenser and look for the capacitor – a cylinder shaped part with 2 or 3 wires on it.
Let SuperTech take care of it for you. Seems like a no brainer, but double check it. Once you have identified the breaker, you will need to switch it off and then back on again. I also tested all of the fuses under the dash and they all tested good. How To Test Capacitor – Ohms Test Only. Also the start/ stop engine button does not light up either, it is on the dash near the passenger seat side. Stumped... No power to climate controls. I just put in a brand new battery too. This problem has been going on for years until i tested the fuses. I tried the heat and nothing, no lights or anything. Looks like the blower relay doesn't even play a role here.... not sure what that's all about.
01-07-2014 08:14 PM. Only an empty relay socket, no label. Terminal 2 is a purple wire and must have 12 volts all the time. In addition, I had the same thing occur twice on my 2005 F350 Lariat. Hoping this will fix things I broke trying to fix things.
