New to me...has a miss

[Brains646]

The plug has a clip but it's just slid over two prongs. nothing is holding it in.

Yes. Coolant temp sensor. I broke the clip on mine when replacing the plugs. Eventually I'll get a new connector, but it has held fine for several months just slid on there.

Edit: is yours unplugged in that pic?

No it's plugged in. Why?

Looks like the sensor itself is broken. I would be checking compression in those 2 cylinders. Possibly head gasket issue.

It must be doing something because if i unplug it the truck stops. Everything works correctly with the cooling system. i checked the plugs and seems that one is getting good spark but the other had carbon on it

Ok,

So I was able to get my mechanic to look at it and we have two bad injectors that are stuck open. I plan on replacing them but can they be cleaned?

They are cheep enough I wouldn't bother

Change the injectors cheaper than cleaning them and less risk that fracturing the injector tips.
The lights and radio could be as simple as the fuse/switch/dimmer switch.Mine was the dimmer switch (bypass it to check).
The rear blower can be one of three things,the control module box which has two wires coming out of it ,the power going to the control box,or the Motor itself .Check if power gets to the control module,if yes check to see if it gets to the motor,if yes it's the motor.If it gets to the control box but not on output from the box to motor it's the control box.If you have none getting to the rear it could be the control panels in the front or power harness behind kick plate driver side behind plastic trim.

Thanks for that info, I plan on digging into the rear blower this weekend or next.

I've got the two injectors on the way and I'll have that done tonight. I also ordered a light switch and all three actuators/motors for the climate control as well as two upper ball joints and the fuel vapor release cannister. All these should be getting installed thise weekend. Hopefully by Saturday night I'll have control over the vents, lights on the dash and a smooth running truck!
