It could be the switch or your blower motor resistor.

It's a safety feature. For example, if there is no oil pressure when you start the engine, you could not see that unless you were in the car and could spin a bearing or seize the engine by starting it remotely and letting it run unattended. So when the check engine light is on, there is something not working properly with the engine/engine management system and it wants you in the car where you can see the guages and turn the engine off immediately if there's a serious problem.

It does sound as if something is drawing the battery down. First thing you need to do is to check the battery...have it fully charged and load tested. Once it's been established that the battery is good, disconnect one cable from the battery and put an ammeter between the cable and battery post. Any draw will show on the meter. At that point, begin removing fuses one by one till the draw stops. that is the system with the problem...then you need to check each component served by that fuse (wiring and relays as well) Your radio will draw a small amount to keep the clock running and some alternators will have a slight draw as well but those should not be excessive.
Ice on the inside of the windshield is often caused by a blocked a/c drain causing the inside of the heater box to have water inside...with the heat on, the water evaporates just enough to condense and freeze on the glass under certain temp conditions. If you have water in the cooling system, (not antifreeze) that can also happen if the core is leaking, but I doubt if that is the case as you'd have larger problems by now than just a bit of ice on the windshield. Under certain normal humidity conditions it can also happen in a normal system so if it only happens once in a while, don't worry about that.

When was the alternator replaced? was it a remanufactured alternator? This is common on GM trucks, fluctuating voltage is caused by a faulty alternator voltage regulator. Have the alternator tested, strong possiblityits defective!!Hopefully this helps!!

Can a 1999 chevy silverado TSS anti theft be draining new battery?


It is possible for anything to cause a draw on the battery.

They way that you can test for a draw by using a multi meter that can measure amperage. Turn off the vehicle and close all the doors. Disconnect the positive terminal from the battery. Place one test lead on the positive battery cable. Place the other on the positive terminal of the battery. You have now completed the circuit with your multi meter. Wait for 30 minutes before you do anything to allow for the powering down of various modules. The amperage should be less than .050 amps after this time If it is more you have a draw. Remove fuses one at a time until the draw goes away. Then focus on all the devices that fuse protects.

BATTERY IS GOOD SO IS THE STARTER AND THE ALTENATOR WHY DO I KEEP HAVING TO HAVE JUMP STARTS? 1997 FORD ESCORT


How long does it take for the battery to go dead, overnight, couple of days?

Have you checked the electrical system for draws? You'll need a multi meter capable of reading amperage. Disconnect the positive cable and hook the meter up in series with the battery and the positive cable. You want to make sure the key is out of the ignition, all the doors are closed and all the dome lights etc are turned off before doing this. If you get a reading of more than .050 amps than you have a draw. You may have to wait for 20 minutes or so for everything to power down to get an accurate reading.

If you have a draw of more than .050 amps than you can start pulling fuses one at a time until the draw goes away and then focus on the things that fuse supplies power to. Make sure you put the fuse back that you pulled out before pulling the next.

If there are no draws and the battery goes dead overnight disconnect the battery, let it sit overnight and then see if the battery will start the vehicle in the morning. Every once in a while you will run into a battery that has an internal draw and will run itself down all by itself.

2004 Chevy Silverado had dead battery after 5 days...


I had the exact same problem! On the third battery and the third time in our local Chevrolet Garage...they told me they couldn’t find any problems. My response was, “this vehicle isn’t dependable and it’s staying here until you fix it.” Well what do you know about a week later and a $100 deductable on my GMPP warranty they found the problem. It was an accumulation of three issues but mainly one.
1. The LoJack system that a different Chevrolet Dealership installed was drawing a constant 20mA when the vehicle was off. Within LoJack specs. Normal.
2. The Prodigy trailer brake controller was drawing 15mA. Within specs. Normal.
3. And the MAIN CAUSE of the whole problem was the HVAC controller never turned off. It was continually drawing 35mA until they pulled the fuse. They had to order another HVAC controller which would have cost $287 and a weeks’ worth of shop hours to investigate the problem. Thank GOD they only charged me the deductible on my warranty.

Battery goes dead intermittently


Quite often the alarm system ends up being the culprit. If you have, or know someone, who has a clamp on amp gauge that can test the draw from that circuit, it should tell you what you need to know. It could be that or a combination of various draws from your system.

Battery dead after a couple of days


Hello you can remove the possitive battery cable and hook one end of a test light to the cable end then the other end to the battery. If the light comes on then there is somthing drawing voltage and make sure everything is off when doing this test .Now to narrow down where it is drawing from . Start removing fusses from the fuse box one at a time and puting back in watching the test light when the light goes off you know where the problem is .
