heat

strange, when I put the heat on full blast warm air (not hot) comes from the drivers side, and cool air blows on the passenger side.

any thoughts a) why its not hot air, and b) why cold on one side of the truck?

I had a similar problem and a new water pump fixed the problem real well. I'm still not sure why I had a bit of a temp difference from side to side.

also, how hard was it to install the water pump?

expensive?

Mine didn't get real hot either. Not a hard job. Was around $150 if I can remember right. Thermostat is like two bits at the auto parts store. All of the above took part of a Saturday morning and my soft top is warm enough to be bearable even when it is zero outstide.

well, it was the simplest fix ever and only cost me 2 minutes of time. apparently when you slide the heat lever up and down it moves a cable under the hood which controls the opening and closing of some sort of valve. well, with the lever in the full high heat position it was not opening the valve all the way. i manually pushed it all the way open and adjusted the cable accordingly. Now i think i can have the top off in the middle of winter, it was SOOO hot in the truck. totally stoked. thanks to all that took the time to offer feedback.

I'm hoping that this is my problem, too.. Will be under the hood tomorrow.

Thank you, Jesus, as I found that the cable was easily pulling the cold on, but not pushing the hot.. The switch for the heater vent is now jammed all the way open, thanks to a little wrench pulling. I'll work out the slack issues once it gets a little warmer outside.. Thanks to all for the advice.
