I already had one failed blend door to begin with but it was blowing cold on the passenger side only, thus making it a low priority for me to fix. At the same time, I had most of the bulbs which were out on the automatic temperature control unit (common known problem on the WKs), so I had the "bright idea" to get replacement bulbs and sodder them myself. When replugging the unit back in its location I saw a little cloud of smoke... all the lights were now working and didn't think twice about it, until I checked the heater control which now was blowing cold air and was stuck in one position. Air flow would not change as I moved the knob around... so, my question is: has the second blend door failed or did my soddering attempt created a short circuit which failed the blower motor resistor? Checked the fuses and all seem ok. Please help: it's getting cold and I am not willing to pay $1,000 + at the dealership. Thanks in advance... Charles.
Cloud of smoke.
you let the smoke out because rule one was not done
remove neg, battery lug first
cars have powerfeeds all over that are hot, key off.
like head lights that is how they work key off
and the clusters, on jeeps have brain, that store data in memory.
this memory is hot all the time. (mine has 3 power feeds in my cluster)
so you you shorted this line , you did in fact burn something up.
that smoke was destruction.
why is a dealer all you know, there are like 100,000 shops in usa not a dealer, check out find ASE shop by ZIP
hark./ all highly trained.
did you scan the pcm to see what errors you have.
or test fuse? yes, test them.
fuses that bad , are bad, (boom)
fuse that seem ok, can be bad, called HAIR line crackes, some are deeply hidden in the fuse. we test them
did you run the cluster self test stated in the free manual>?

RTM read the manual first then leap. and win.
Testimonial: "Thanks a lot Juriy! You're right... Guilty as charged on the battery neg... this is where lazyness gets you! On a side note though, the reason for my post was that I had indeed taken it to my local mechanic who checked out the fuses and relays, hence leaving me with the less than desirable option of going to the dealer. I can also try another mechanic but before that will test all the fuses to be 100% sure... maybe my mechanic did what I did: only a visual inspection. Anyway, your reply was highly appreciated! Best Regards, Charles."
