95 jeep cherokee. my heat & ac won't blow.

Your jeep has an electric fan which should come on whenever the AC is on or if the temp goes over the 1/2 way point. It is fed by a 20 amp fuse in the engine fuse box. If the fuse continuously blows, replace the fan

check all the fuse box first .

If nothing is blowing at all then you need to check the fuse, check voltage at the fan by turning on the switch if no voltage then the switch is bad, if voltage and no fan then the fan is bad.

Lets Look at the fuses once more the # 2 threw 5 i have seen the fuse be good but it had loss contact in the fuse box, remove the fuse and install them to see if this helps
Also at the battery there is a fuse link check here to see if this has blown or loss contact,, a new one can be spliced in if needs replacemint

CIRCUIT INFORMATION
(What the fuse is for.) 1 25 Amp Rear washer / wiper - Located just right of top center in fuse bank. 2 15 Amp Radio, Cigarette lighter 3 25 Amp Heater blower motor - (* - if this keeps blowing or you only have heat on one speed check your blower motor resistor pack.) 4 20 Amp Turn signal, Back-up lights, Rear window defogger relay 5 10 Amp Dome light, Courtesy lights, Glove box light, Cargo light, Radio memory, Power mirrors, Teltak connector (For old analog "bag" cell phones, I think.) 6 15 Amp Hazard warning lights, Brake / Stop lights 7 10 Amp Parking lights, Headlight Warning Chime/Buzzer, Instrument panel light dimmer 8 7.5 Amp Gauges, Instrument cluster, Seat belt warning, Headlight delay, Chime module, Overhead console 9 5 Amp Instrument panel illumination 10 25 Amp Rear window defogger 11 30 Amp
Circuit Breaker Power door locks, Power seats, Trailer towing wiring harness 12 10 Amp ETR (Delco OEM) radio, Power antenna 13
(1984 - 1987) - - - Spare Fuse (GM automatics and manual transmissions.) 13
(1988) 7.5 Amp Transmission control unit (For AW4 automatic transmissions) 14 25 Amp Headlight delay, Horns, Security alarm 15 5.5 Amp
Circuit Breaker Front windshield wipers 16 30 Amp
Circuit Breaker Power Windows 17 10 Amp Clock, Security alarm (Ignition)

probably needs a new 'resistor pack' (it alters the fan speeds)

check the fuse for the blower moter. fuse #5 (30amp fuse). the blower might have gone bad as well.

try recharging the ac

There are broken wires in the wiring harness between the frame and your driver's side door. These wires control all the windows and door locks in a 95 Jeep. Same thing happened to me. You will have to cut the rubber boot to get it off and check which wires are broken and repair them.

fuse should be third up from bottom on right...25 amp. Or, 40 amp in power distribution center.but I believe that part of system is for ac compressor. If fuse blows again, likely motor is worn out.

1st, the fuse location is marked, what is the 20 Amp fuse for? 2nd, did the smoke have a nauseating sweet smell to it? If it smells like described it is the heater core leaking, coolant steam looks like smoke.
