No heat after Taco whip antenna mod

[MN4runnerman]

So to get it out of the way the vehicle in question is my 99 5 speed. Last week I did the Tacoma whip antenna mod and had the dash disassembled to remove the old antenna. The only thing I unplugged was the old antenna and then I plugged in the new one. I left everything else plugged in to the AC module just unscrewed it so I could move it around while doing my work. Now it's gotten a little cold outside again and I go to turn on the heat but there is no heat. AC works fine the blower works just no heat. Anybody know where to start or if I need to describe the problem better?

Thanks!

Have you checked to see if the heat valve in the coolant line is operating? Might be you knocked the end of the control cable off under the dash.

Pop the hood and make sure the valve is opening and closing as you switch from cold to heat. The valve is located under the hood on the firewall in one of the 2 coolant lines that go through the firewall. If hot coolant is indeed flowing you should be able to feel it in the lines.

Good place to start.
