      Intermittent issues can be a pain to track, you have to test when problem is ongoing, meaning, check voltage and ground at the headlamp connector wiring when problem is ongoing. Go from there.

      Did you check voltage at fuse circuit? Even if fuse is good, if no voltage, the circuit is still dead. For the htr/ac, I saw two fuses, one is hot all the time, the other goes hot with key on. If no voltage on the one that goes hot with key on, yes, have to check voltage and from ignition switch.

      Click on the link for heater/ac,

      I checked the Hot fuse and get 12.7 volts. But when in Run or accessory I get 0 on the switched fuse. Also the wipers do not work. Is there a relay that controls the feed or does it come directly form the ignition switch?

      Click on the link for ignition switch wiring, I see 3 hot circuits that carry voltage to ignition switch, In the diagram, top wires. Check ignition fuse a--ignition B fuse, ignition fuse c for voltage, hot all the time.

      Several possibilities; faulty daytime running light relay, faulty daytime running light control module, fault in the wiring or connections common to the DRL circuit.

      The parts are readily available from these many on-line sources, www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities. In fact they, (RockAuto) list the DRL relay from around $8.50, and the DRL control module from around $33.00 for your vehicle.

      Check and / or replace these items as possibilities; fuel guage fuse, faulty fuel level sensor (as component of the entire fuel pump).
      It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Generally recommended to have the complete fuel pump module replaced on high mileage vehicles.

      The new fuel level sensor costs around $22.00, and the new fuel pump assembly costs from around $83.00 to over$269.00 for your vehicle - from these on-line auto parts sources; www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities

    Climate Control unit not working
    Air flow is stuck on defrost and will not go to AC or vent so air only blows thru defrosters

      Most likely the issue is a faulty blend door actuator. Easily replaced - located just next to the heater blower motor under the instrument panel.

      The parts are readily available from these many on-line sources, www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities.
      In fact, they (RockAuto) list the blend door actuator from around $35.00 for your vehicle.

      There are two separate actuators in your truck. One is a blend door actuator and the other is a mode door actuator. The BDA only controls the temperature of the air and is unrelated to which place the air blows out of. The MODE door actuator is responsible for where the air blows from. That is what needs to be replaced.
