Question about 1999 Chevrolet Blazer

1 Answer

I posted this but was unable to receive a solution so I'm posting it again. Battery drain overnight. Nothing turned on to drain battery. Traced it to the a/c compressor. Removed fuse to compressor and no drain. The Haynes repair manual says the PCM is deffective. What would cause the compressor to drain the battery? Could it be a bad PCM?

SOURCE: no power to ignition 96 camero dl

Check the wires to the distributer or to the modules could be poor or no conection. If you can turn the car over but no spark it's probably something to do with ignition, distributer, module, or wiring to the ignition.

SOURCE: When the ignition key is turned a clicking noise is heard.

Sounds like a bad ground. If the battery voltage does not drop when the starter is engaged, the starter is not getting the juice. Check the ground connection again. 90%

New battery - battery is drained in the morning.Replaced voltage regulator. Disconnected aircon. Still drains overnight. Ute will start and run with full battery but it drains overnight.


Easyest thing to do is pull one cable off your battery. Start pulling fuses and each time touch the cable to the battery post. When you find one that reduces the spark drastically that is the circuit to investigate.

I have a 03 Expedition that on the first time you try to start it will turn over but will not fire. When you turn it to the off position and try to start it again it doesn't turn over and says nothing


I'd be looking at the condition of the battery first.

Have you tried using jumpers to see if you can get it started?

Tried disconnecting the battery and leaving it on a charger overnight? Cleaned the terminals and battery posts, cable connections?

Lets try that and then see what happens.

Cheerfuls!

Dodge truck battery drains overnight. new battery installed


Seen this "mystery drain" many times. Check spark at the battery to see how big the drain is. For this simple test, blow away any (explosive) battery charging fumes. Leave one terminal on and gently touch the other to its post in fairly dark surroundings. Then try it again with the wires taken off the alternator. Your spark is now probably much less. Usually bad diodes leaking electricity backwards through the alternator cause this drain. Replace the alternator or the diode pack inside it. Some mechanics recommend actually measuring the drain.... hahaha. OK whatever.

The Battery is unable to turn the engine, recharged it & the engine fires up, but overnight the battery is drained again. changed battery for new, same results.


Temporary solution until you find someone who can fix it. As soon as you are done driving, unhook one of the cables on the battery, and then hook it up again before you try to start it next time.

Why does my 96 Cadillac Eldorado battery keep discharging?


First step have the battery tested, a bad cell can cause a internal drain and kill the battery, if the batt is ok then check for interior lights like visors that stay on or interior light that come on by themselves at night due to defective door switches.

My 98 lumina has a constant power draw from somewhere. I just replace the battery and had the alt tested (it was good). I have to jump the dang thing every morning but if I drive it enough during the day...


The alternator may charge fine but could drain the battery through a bad diode,have you checked the alt for a bad diode?Disconnect the battery positive cable.Put a regular 12v test light between the battery positive post and the positive battery cable.If the test light is bright you do have a drain,if dim it is OK.A dim light may mean the drain is internal in the battery.If you do have a bright light remove a fuse ,one at a time from the fuse box until the light goes dim.Once dim you have identified the bad circuit.If removing all fuses do not dim the light,disconnect the alt charging wire at the alt,if that dims the light,then you do have a bad diode.DO NOT create a drain(bright light) when checking for the drain by turning on the key or opening a door/trunk etc.
Also,do an overnight battery check by disconnecting the battery overnight,if things are fine the next morning after the battery was disconnected then it is a drain in the vehicle,if the battery is dead even after being disconnected overnight,,then the battery is bad.

Batery drains overnight


dissconnect one cable from battery. hook a test light between cable end and battery post. ( light on test light will come on if current is drawn). pull out fuses from fuse panel untill light goes out. that circuit is the culprit.

buy a test light at auto parts store. and wrench to dissconedct batt. also buy battery post cleaner.
