I appreciate your feedback. I'll follow your troubleshooting advise as soon as I get a chance to do so. Sounds like the best place to start. This is my secondary vehicle and my beater mostly used for utilitarian reasons. Got a good deal on it when I decided to replace my 84 GMC S15 2WD long bed. Done a bunch of small fixes to it with a few still left to do. Now I find myself driving this little jewel more than my SUV. I'm a penny pincher and a DIY'er so throwing a lot of money into this truck isn't an option.

Though not as warm as where you are it has warmed up to 25°F here. That's considered a heat wave in these parts.
I'll repost and keep this topic updated as I figure this out. Thanks.
