My heat doesn't work anymore the fan works fine but its only blowing cold ,thought it would be the blend doors because its common on the limited models but took apart the dash and its fine. also checked the heater hoses for trapped air but seems fine. the fault codes i have are 48 54 55 56 which indicate the blend doors but as i said they're good. luckily i live in Australia and its always hot during the days but the nights get cold in winter and no heater is a pain in the ass good thing the heated seats work still so my butt doesn't freeze haha

I had a 1993 Jeep Grand Cherokee limited v 8 5.2l. Bought it used, great car for many years. I bought this good looking 2000 Jeep Grand Cherokee Laredo about three months ago. This has been a night mare. Started leaking antifreeze 2 weeks later, so I had a water pump put on. Three weeks later a leak was coming from the radiator. Then I replaced the radiator plus the hoses top and bottom. While all of this was going on I had no heat. The fan would blow but no heat. So I had a thermostat put in.

The engine comes to the right temp but no heat comes thru. Now I am cranking it up and put it in gear nothing happens. I let run for about ten to twenty min. Then it drives fine the rest of the day. Every now and then as I am driving I will hear a clunk from the transmission. This thing was making a rattling sound when hitting the smallest bump in the road and it just keep rattling. All 4 shocks were shot. I had these replaced . I still have a small rattle and don't know what it is. The new shocks stopped the bad vibration that came when the Jeep speeds over 60 mph. What a pile of junk.
