OK, this is starting to REALLY piss me off. All I want to do is wire in a simple aux fan switch. But nooo, it can't be easy...
Here it is from the begining....
I have a 1990 Jeep Cherokee Pioneer w/ the AW4 tranny and 231 TC. It's getting a bit warmer around here and the XJ started to overheat a bit while idling in traffic, since the aux fan wasn't kicking on.
So, I found Craig's write up, http://www.olypen.com/craigh/auxfan.htm .
I went out and bought a two position lighted rocker switch from Shucks. Following Craig's directions I ran, I spliced into this orange wire, shown here:
Picture does not show the splice, just references the wire. I than ran the new wire through the firewall to my rocker switch.
Once this was completed, I plugged a wire into a slot in my fuse box (hot when ignition on) and ran it to my rocker switch, as seen here:
Picture does not show the wire I plugged in, just a reference of my fuse box. I just want everybody to be on the same page as I am. I
Once this was done, I wired in a ground for my lighted rocker switch, and installed it in my console, as seen here:
Once everything was wired up, the switch seemed to work great. I don't remember exactly, but I was messing around with my AC settings, and may have turned on the AC while I had my aux fan switch running. Anyway, I do remember both my fan and AC working just as normal.
The next morning, I start my XJ up (aux fan switched off), and turn on the AC. It comes on for a few seconds, I hear a "crack", and it stops blowing. Sure enough, 25amp blower fuse is blown. I replaced the fuse, turned the AC back on, and the fuse blows again.
I test my fan switch to see if the aux fan will come on, and it works fine as it did the day before. I decided to do a bit of experimenting, and I unplugged the power from my fux box which went to my new rocker switch. The blower still blew the fuse. After a little head scratching, I unplugged my AC clutch fan control switch (do not know if this is the proper term or not), and presto, the blower stopped blowing fuses but would no longer blow cold air.
A couple hours later I had the crazy idea of removing the splice on the orange wire. I plugged the AC clutch fan control switch back in, and sure enough, it didn't blow a fuse. But at this point I was right back where I started.
So I jumped on the forums, and told me I didn't even need a power for my rocker switch, and to just wire it to the black wire and the white wire on the fan, as you can see here:
So, I sliced into these two wires below the connector plug for them. Now one of them was black, and the other was red with a white stripe.
Here is a picture of them spliced in with the wires to my rocker switch:
Connections look a bit rough, but trust me they were good and solid. After I was finished I fired up the old XJ, and turned on my rocker switch. It didn't light up as it had done the first time, and the fan didn't come on either. Honestly I wasn't really suprised. I turned my AC on to see if it would blew a fuse, as it had done on my first attempt.
Well, it didn't blow a fuse, but I quickly smelt the awful smell of melting rubber, or similar burning stench. I quickly shut my car off. Since the fan switch didn't work, I sniped the new wires a couple inches before the splice. So it was basically as it was before I started.
I started the XJ back up, and turned the AC on. I didn't get the burning smell this time, but my aux fan wasn't turning on, as it usually does with AC or defrost. The engine was pretty cold, so I drove around a bit with the AC on max, hoping my aux fan would kick on after the engine warmed a bit. I kept hearing the familar "click" or "pop" before it turns on, but it just never came on, dispite the clicking.
So basically, I am right back where I started, except I now possibly have a fried aux fan and or aux fan wiring. Is it possible my switch could now also be toast?
Someone please help me figure out what I am doing wrong and why I can't get something this simple to work. It's REALLY starting to piss me off.
Sorry for the long post, but I need help!!
Thanks
