    Okay, so I still need to do a little more digging and cleaning but figured I would throw this out there before getting too meticulous on the cleaning.

    A few days ago I went on a little adventure and ended up pretty covered in mud by the end after all of the rain we had here in Texas. I have since noticed that my air conditioning is no longer as cold as it was (especially at idle, it cycles from cold to as hot as ambient air). I noticed that the issue is not really present while driving although it is possible it is not as cold as it was before. I ended up sitting on the blacktop waiting in a line at idle with AC going since it was 95F + outside. I noticed the AC was doing this cycling issue again and was struggling to keep it even remotely cool inside. I also noticed eventually that my engine temp was higher than average (although didn't ever pass the last bar on the gauge). If I revved the engine to around 1500 RPM I could get the AC to blow cooler while sitting still. I have not noticed this issue in stop and go traffic, only while sitting idle for extended periods (min 3-5 mins and up).

    I have tidied up most of the vehicle from mud, but am wondering if there is another place I am missing that is being insulated by a layer. I plan to remove skid and clean under well later today, but I have done a fairly thorough wash so far to remove as much as possible.

    Any thoughts on possible problem? The main fan is spinning when the vehicle is running (and spinning faster when AC is on) so I don't think that is the issue.

    I have not checked the AC lines for leaks, so that's a possibility I suppose if the compressor just isn't getting enough power at idle to compress the R134A if it is low. Only thing that bothers me about this is the temp gauge that was running a tad high meaning that the problem was not only with AC compression system

    Any other thoughts?

    Forgot to mention, I do have climate control in the vehicle, and I have tried lowering fan and turning temp colder and vise-versa with minimal difference.

    Seems like you have a engine cooling issue and something up with the ac. Id take it to the dealer. Not once in 40k has my truck needle gauge gotten over the halfway mark. So i would start there.

    That was the plan, I just wanted to make sure I removed any possible mud that may be hidden that they could find and complain about prior to going in :)

    I only have around 25K on it hah.

    Anything blocking the radiator or condensor?

    Is your cabin air filter full of dust?

    Cabin air is behind the glovebox if your curious. Access from inside the cab.

    Good thought, I should check and make sure the filter is not clogged. Although they did "give" me a replacement filter last service that I installed myself since I left my glovebox locked haha.

    Ever get a solution to this? Having same issue minus engine temp. Recharged ac (didn't really need much, was nowhere near out) still air isn't cold while idling and not much colder while driving.
