#56 of 61 '97 Cav Fan Speed Switch Issues by dkf Aug 14, 2008 (4:27 pm)
I saw a prior posting that I believe will apply to this case as well, but I wanted to get a little more information. The lower 2 speed settings of the fan switch do not work, but the higher 2 speed settings work fine. A poster had mentioned that this is a blown resistor (or in this case perhaps 2?). My questions are:   1. If I'm looking to replace these resistors, what do a look for? Would they be called "fan speed switch resistors", for instance?   2. Would I find them at an auto parts store like Pep Boys, or would I need to go to a dealer?   3. Once the blower motor is removed, is it "obvious" where the resistors are located, or does it take some fair knowledge to figure that out?   Cheers,   Doug

I have worked on everything my entire life (not certified) and am just looking to confirm my belief of the blower motor/fan!! any help?? Thanks for your time in advance.. I know this is going to take like hours so...thats expected!

My inst panel quit working, So i took out the cluster fuse and got all the gauges to work, but now my a/c turns on but i cant change the speed nor can i change like from floor to defrost. It blows cold and it blows a lil out of my floor vents and out of the dash vents and a tad bit out of my defrost. I can change from cold to hot and

Replying to: goddude (Oct 11, 2005 7:09 am) I realize this is an older post; but seems to be a re-occurring problem. The cable that connects on the backside of the climate control knob is known for kinking. If the cable is not frayed yet, you can pull it off the back of the knob and straighten it (this does require, laying on your backside on the passenger side floor, and a flashlight helps if you are trying to accomplish this for the first time....if the cable is frayed you can replace the cable. It is the same cable as the "heater control cable"; to replace it, it is a job that can be done without removing the entire dash, you will need to remove the plate over the brake; and again, plan on a lot of time on your back with a flashlight. I just replaced mine over the weekend, and was able to straighten a co-workers today. Replies to this message: cavpains (Aug 31, 2009 5:49 pm)

Replying to: badger1888 (Jul 24, 2009 8:23 pm) I also have discovered the air control knob kinking. I fixed it using a need nose pliers but it just wants to kink again because the control box wheel or control box "guts" must jamb at times. I have checked for clearance and there is no rubbing on the wheel by the cable. Question - what is the specific cause for the failure? Has a air gasket come loose inside the air control housing that interfers with smooth operation? Also, with all my "experimenting", I found that if you allow hot air to heat up the air control box, the control knob will then move freely to all positions. another method that works with my size 13 fingers, If you can find the cable with your fingers while sitting in the drivers seat, You can force the knob while using your fingers to keep the cable from kinking.
