I did swap in an air box air box from a 93 XJ which kind of crushed the air hose down, and I took off the map sensor and hose to let a friend borrow and see if it would fix his problem, also I removed the throttle body to take some pictures of it to see if I could get it bored out. I don't drive this jeep often, today is the first time in probably a month, so I'm not 100% sure when this started

Wondering if this is normal or if they are blown? I also have some pretty bad tread ware of my front tires.

I am a senior in high school and I am second year auto tech student. I went through the Jeep changing the fuses and even changed the bulbs and switch. I have no idea what to do rn. I have asked the shop teacher if I could bring it in and he told me yes but I have to wait until almost winter to get her in. I need some help trying to figure out the problem so I can get her insured.

I checked the fuse in position 25 marked ABS, Climate Control. Fine. There are three block type fuses that look like relays but they are described in the manual as circuit breakers for the power windows, power seats and front wipers.

While trouble shooting I noticed the check engine light was on. When trying to test to see if the blower motor worked, I also noticed the electric cooling fan was not coming on when I turned the AC on.

I was near and Auto Parts store that offers a free diagnostic. Came up with code "p1491 Fan Relay Circuit"

are the electric fan and blower motor tied together?

I still can't find the relay. I did some searching on this forum and it seems that there might be a relay under the dash where the resistor is located. Does that sound right?

Too bad this is different from the 98 i have because i finally was able to find my way around on that one. This one is a 2000 Limited and has factory remote start and power seats and some other bells and whistles.

Changed the cooling fan relay under the hood. Cooling fan did not come on.

I do not want to take it to a repair shop so they can charge me a couple hundred to change the blower motor relay.

Could this be a more complex electrical problem?

Any help or suggestions would be helpful and appreciated. Without the knowledge and expertise of the members of this forum, I do not think I'd be able to afford to own an older XJ. (which would suck because I love them).
