Cold Air Blowing

I spent the majority of the winter driving around in a truck with a worn out blower motor and luke warm air trickling in, I put up with it for too long. I had enough and decieded to replace the blower motor and while I was in there I cleaned out the ducting and did a once over on the linkages and things before re installing it in hopes that it would warm up the cab a little. Well it didn't. It silently blew barely warm air. I also had noticed that the temp gauge in the cab always reads at the coldest reading, there was only one time where it jumped a little bit after driving for a long time, I had assumed that the gauge was just broken but I was wrong again! I decided that the thermostat had to be either broken, and stuck open or there was nothing there at all. I was right, there was nothing in the thermostat spot, hence the "broken" temp gauge and cold air blowing. Now I have a temp gauge that reads in the norm and enough warm air blasting silently into the cab to make it uncomfortable! word!

Before I go 3 things:
1. My tenses in my blogging are all wrong and I know it but whatev, gimme a break! I'll work on it!
2. Thermostats have a right and a wrong way to install them. FYI the spring goes into the engine and the "point" points out at you.
3. I have noticed, and its not a suprise, that the heater core has devoloped a slight leak that I can smell with the heater on. It is not enough to make a mess yet but you can expect an update on the fix. Good news though! I happen to have an extra one of those that came in my box-O-junk I got from a guy on craigslist a while back. YESSS!
