In my 1999 jeep grand cherokee limited the blend door for the heating/air conditioning make a ton of noise, and fail quite often. It is a huge problem that is very expensive to fix and every dealer tells me it is a problem straight from the factory.
1999 Jeep Grand Cherokee visibility complaints
Page 4 of 7: complaints 71 to 100 of 165, newest first, as owners wrote them.
Two problems: 1. The blower motor resistor burnt out and the AC/head fan quit working. It was sparking when I managed to disconnect the wire. Luckily, I was stopped and could reach it in time - had I been driving its very possible my vehicle would have burnt up. 2. No heat. Entire last winter I was forced to drive 2 hours per day constantly wiping fog off my windshield. I was told by a 'mechanic' it was a clogged heater core so I had to put up with it because I did not have the money to fix it at the time. Dangerous and cold, but I had no choice. Now I am trying to get my vehicle repaired I start researching and find there are entire web sites devoted solely to these two problems. 1. Blower motor resistor shorts out. To properly repair you have to replace the resistor and the dashboard wiring harness... Very costly!! $600+ 2. No heat due to bad blend doors. $1200+ 3. Both of these appear to affect jeeps 1999-2004 year models how can jeep continue to knowingly sale automobiles with 1 - a fire and safety hazard with the faulty resistor? 2 - a safety hazard with no heat due to faulty blend doors? Google it... Both of these are very well known problems with these vehicles and are not isolated incidents. Please look at these two links provided. They just start to scratch the surface of how bad this problem really is. Jeep should be responsible for repairing both of these problems as they are both safety issues and they knew about them prior to the sale, not to mention the cost of repairing these items places an unfair burden on the owner since fair trade would mandate these known and recurring defects should have been disclosed prior to sale. These are not rare or isolated incidents, they are known problems jeep failed to disclose or repair.

Visibility: defroster/defogger system:windshield:blower blend door failure - tsb
The automatic HVAC system on my jeep grand cherokee has broken. The "blend doors" that control hot vs. Cold air do not function properly. As a result, cold air is blown when hot air is required. This is a known issue that thousands of owners are experiencing on their wj limiteds and overland editions. This can create a dangerous situation by not blowing hot air required to defog the windshield. The issue only occurs on models equipped with the automatic HVAC system.
Visibility: defroster/defogger system:windshield:blower . Heating system continues to fail which presents a safety hazard when I'm driving and the windows become fogged over. Some days the defroster works but most of the time it does not. The unit continually blows cold air out even if the heater is on.
Both blend doors and/or HVAC door stops have gone out. No, heat which means no window defrosting.
Very unsafe malfunction of the "blend doors" in my heater mechanism. My father's 2003 has the same problem. Heat and defrost air only comes out one side, can't see out all the windshield!!! Dealer knows about the problem, says if you only have one bad one, might as well replace them both with the new redesigned parts for $1600 - $1800. Help!
1999 jeep grand cherokee ltd, blend door on HVAC/defroster stopped working.
Climate control unit faulty, "common" fault with this vehicle make / type, climate control unit unable to maintain temperature, blows cold when it shouldn't be, I am informed it is a fault with the blend doors, and to repair is very very costly as the whole dashboard has to be removed, parts are available but cost of repair is very expensive.
Fogging of windshield due to improper design of the HVAC on my jeep. This si the second time it has broken, with only 55,000 miles on my 99 grand cherokee limited.
I have a 1999 jeep grand cherokee, and the passenger side blows hot air even when the temperature of the dual climate control is set lower than the driver. I have read in forums and many other jeep owners have the same problem.
Hearter blend door in heater box not turning.
The heater fan in my 1999 jeep grand cherokee stopped working and there was a burning smell in the car. Mechanic found that the fan resistor (computer) and pigtail that connects to it were burned up. He checked with jeep and there are 3,000 of these items back ordered because this is a problem on many of these vehicles. Its winter and 17 degrees in my car I could freeze with my family or my dashboard could catch on fire.
No heat on passenger side - due to the infamous "blend door" problem.
Visibility: defroster/defogger system:windshield:blower AC/heater/defroster blower no longer operates properly. Ac self-diagnostic codes indicate "temp door/recirc door travel too large". No combination of control settings will make the blower/fan operate.
This is concerning a 1999 jeep grand cherokee limited edition, I am writing due to repeated problems with the defrost control inability to clear or keep clear the windshield. Cold outside air blows from the defrost vents, and does not clear the windshield of frost or moisture, or causes moisture to re-freeze. This is caused by the failure of the blend doors in the heating system. This occurs while driving after allowing the vehicle to warm and the windshield to clear. This is a re-occurring problem, the dealers service manager says that all wj series jeep grand cherokees with the dual climate control will have this problem and will cost between $1200 and $1800 to repair and that the repair is not permanent, just a fix until the parts breaks again. At this time this has not been repaired at the advice of the service mgr of my jeep dealer, he recommended filing this complaint as he says there should be a recall on this issue.
99 jeep grand cherokee limited will only blow out cold air. No heat at all. Get AC codes of 52, 54, 56 from the diagnostic screen.
Rh side including defrost duct blows out only cold air, making defrost on the rh side difficult.
The climate control on my 1999 jeep grand cherokee will randomly create loud creaking and crunching noises from under the dash and will cause a sudden drastic temperature change. This causes the defroster not to operate correctly and the windows to instantly fog up. This first occurred in october of 2005 and has happened over a dozen times reducing my visibility sometimes to nothing at all. The dealer cannot find any problems and will not investigate any further.
Blend door broke on passenger and driver vents. Blows only cold air.
Blend door failure causing fogging of windshield.
The HVAC system on my 99 jeep grand cherokee is faulty.
Wj jeep grand cherokee blend door breakage/failure visibility: defroster/defogger system:windshield:blower.
Hvac on my 1999 jeep grand cherokee ltd. Has failed and the system only blows cold air. This makes the vehicle inoperable in cold days of winter: windshield cannot be properly ventilated. This happens to almost 100% of these vehicles after just 50k miles. And even the dealership says it happens to all models 1999 through 2002 or 3. This should be a recall item, not a tsb! Right now it's just a chance for jeep to make an extra $1,800 off of a factory defect.
1999 grand cherokee limited blend door problem this problem is on every jeep I read about this is a massive error on jeep there should be a recall.thanks, normand.
(1) no warning (2) cold air coming out of passengers side heater vents all the time, also this makes it next to impossible to defrost the passenger side windshield. (3)I was told it cost $1200 to fix this, and I do not have the money right now to do this.
Blend door failure. Cost $1100.
Defroster/defogger in my 1999 jeep grand cherokee limited is non-functional. The passenger side has no heat at all, but my main concern is the defroster which makes it impossible for me to see out of my windshield now that colder weather is here.
I'm having issues with broken blend doors and recirculation doors on my 1999 jeep grand cherokee with the dual zone climate control.
Cold air blows from one side of the dash even when you have the heat turned on making defroster inoperable in the cold. This is extremely dangerous in the cold. Dashboard has loud creaking sound coming from its underside when ventilation is turned and creaking from the dash seconds after shutting the engine off. These jeeps are known to have this severe safety issue.
