Default Cold weather behavior: battery, signals, dome light

I've been having an issue with cold starts. When it gets down to about 5 F (as it does here in Iowa) the battery can become too weak to start the truck. A jump is then required to get it going. This can happen after just a couple of hours in the parking lot on a cold evening. Also, the turn signals will "freeze" and not work, or work sluggishly. Sometimes the dome light will fail to light as well. You might think this is a cold door switch, but the slide switch won't get it on either. These are cold weather problems only. Could they be related? My next step will be a new battery, even though the one I have in there is only 18 mos. old. Advice?

get the alternator checked , it may not be put out enough to charge the battery . do a load test on the battery to see just how good it is

Your battery has reached the end of it's useful life. A new one will fix the problem.

Changing the alternator is not going to fix a bad battery. If you're getting 13-14 volts with the engine running, then the alternator is doing it's job. Your engine would be be stalling out if the alternator was shot too because it wouldn't have electricity to run let alone start.

Definitely check the battery first. Because every time that battery dies it shortens it's service life and your battery may be dead already if you've let it die a lot.

Smile Re: Cold weather behavior: battery, signals, dome light

Thanks to everyone for your replies! I've since purchased a new battery and all is fine. The new one has a substantially higher rating for cca. I have had no problems afterward. However, it's been unusually warm around here for this time of year. If we do get a few -15 F mornings like we normally would ??? We'll see!
