Ok, so I am going to my classes, and my truck is STILL not heating the cab up, so I look at my temp. gauge (i am now at about a mile after where it usually cuts on good) and it is just barely past the line for normal, usually its almost half way there...
I get to the school, and its not even 1/4 on normal.
I open up the hood, and my A/C compressor keeps kicking on, with the controls set as far as it will go for heat, and on panel/floor. So i turn it to panel only, still doing it... turn it off, it stops. Turn back to panel/floor, still doing it. Cut truck off and then went on to my classes to worry about this later. It does blow on panel, floor, and both, so it cant be the contact points can it?

Now I DO have E-fans, which I used a DC Controller to wire it in, and when the A/C is on, the fan is on full blast, at least I know my fan works VERY well now...

What is the problem?
Is it the controls for HVAC going bad (contact points?)
Is something just terribly wrong with A/C compressor?
Is my controller at fault?
It is wired directly into the pos. wire for A/C, i guess when voltage is present, the controller cuts the fan on...

I would like this solved.

On the way home though, everything worked out perfectly...

I might have mentioned contact points alot, I just want to get this thing figured out!!!

 

I do not want to be wasting power and gas, or the compressor life or refrigerant...
Also, the compressor would come on for about 5 seconds, then stop for about 2-3 seconds, repeatedely.
And when I turn my setting to off (since the day I got the truck) it still blows on the floor at low...if I turn the heat on it blows heat, if I turn it to cool then it blows cool, why does it do this too?!

Mainly I want the A/C thing fixed.
I want to know what is going on with it...

 

The compressor is designed to run in almost all of the positions. Especially defrost to help clear the windshield. I think that floor, and panel positions won't allow the ac to run. Sounds like you could just have a thermostat that's not cooperating. Don't worry about the A/C, that's normal.

 

Where is the coolant temp. gauge at?
Is it past the thermostat?
If this makes no sense, im wondering if the thermostat kept closing if my gauge read almost right on the line of normal, if my engine coolant temp. was actually higher, do not want to overheat or anything.
But then again, warm coolant must have been going into the heater core...

 

Your coolant temp gauge is in the instrument cluster. It goes N O R M A L. You sound like a chihuahua on cocaine. Slow down. You probably just need to replace the thermostat. That's it. Don't try to decifer the truck. How are you going to "overheat", if you are only getting to the "N"? Overheating would be way past the "L".

 

What I was asking is if the sensor for the coolant temp. was before or after the thermostat.
Cuz if it was before, then it would be sensing the temp. before it goes into the engine, and if the thermostat is not open, then that means that the coolant inside the jackets in the block is not being sensed, therefore it may be overheating...
and sorry for not spacing out normal?

 

Just busting your chops. The sensor is after the t-stat. Still probably a bad t-stat, though.

 

If your truck was overheating it would be missing like crazy. These cooling systems in our trucks are very efficient. replace the t-stat bro. The T stat does the grunt work of the cooling system opening and closing all the time.
