Having problems with your 1999 Jeep Wrangler ?
The fan for the air conditioner and heater will not come on for any speed on my 1999 4 cly. jeep wrangler. I've changed the fuse in the fuse box behind the glove box. Is there any other switch/fuse that I should check?
It may be a relay problem. From the controls on the dash it should lead you to the components behind the dashboard. Check if the connections are OK. I am unsure if the relays are found there, but inspect the relay at that area or under the hood.
