86 xr7 2.3

This might be a dumb question but here it goes. Last fall fan worked fine but now (not that its very warm here) it has yet to come on. The fan motor is nearly new and the control unit(behind the glove box is new). I ran a jumper to the fan motor and it ran so I know its ok so my ? is this. Where is the temp switch located at and can that be tested to see if its functioning? Thanks in advance for any and all suggestions.

The fan should run if you turn the A/C on. If it runs with the A/C the problem is the fan switch or the wiring to it.
If it doesn't run with the A/C  it gets back to fuse link K or the ignition switch. If the ignition switch is the problem, the turn signals won't work.

A/c hasnt worked since I've owned the car so is there another option to test the temp switch? I know I had a ignition switch problem as I just replaced it a couple weeks ago. Man , let the car sit all winter and everything went to heck.

Unplug the connector on the fan switch and jumper the two wires together.
The fan should run with the ignition in run.
If that works, it just leaves the switch as the problem.
Do you have a meter if we need to trouble shoot further ?

Ok, switch got ordered and when I got there to pick up it has 2 round male pins and I know the plug I jumpered to make the fan work was 2 spades(very small). Anyhow, are there multiple choices? or is this just more of my good luck with AutoZone? Also how much coolant should I expect to loose when I finally get this straightened  out?

Yes thats what I have, I believe Autozone ordered a temp switch but for a 87 as I looked one up on line and it looks like what the kid had.

You probably don't want to use the word "temperature" when talking to the parts people.
There are temperature switches and sensors that are for the dash indicator and the EEC.
You probably got one of those.
NAPA calls it "fan switch"
