The blend door that directs HVAC airflow is the dominant complaint in this cluster. Owners describe a fragile plastic door that breaks at a single mounting tab, then either jams closed or falls loose inside the ductwork, blocking airflow entirely. Dodge redesigned it for 2007 with two metal tabs and stronger housing, but refuses to recall 2002–2006 trucks despite widespread failures. When the door fails, defroster output vanishes—windshield fogs or ices over at highway speeds, forcing drivers to pull over or narrowly avoid collisions. Multiple owners report paying $800–$2,000 for repairs that involve removing the entire dash. Some dealers perform incomplete repairs, replacing only the door instead of the housing, leading to repeat failures within months.
Windshield wiper failures also appear in the narratives—wipers stop mid-drive or work intermittently despite a recall being on file. One owner says Chrysler refused to honor the recall, claiming the VIN didn't qualify.
Heater control malfunction—where air doesn't blow from the selected outlet—creates unpredictable heating patterns and defogging failures. One owner replaced the control switch and actuators for $800 only to have the problem return.
A single complaint cites rear window leaks causing mold. All visibility issues tie directly to HVAC system failures that Dodge has acknowledged but declined to recall.
Failure modes owners describe
Blend Door / Recirculation Door Failure
The plastic blend door (also called recirculation door, deflector door, or flap) that controls air flow direction in the HVAC system breaks or jams, typically due to weak plastic construction or a single mounting tab that cannot withstand the impact of the door closing. Owners report the door either breaks off inside the ductwork, gets jammed closed, or fractures at hinges. When broken, the door blocks airflow and restricts the system's ability to direct heat, cooling, or defroster air.
When: Failures reported between 22,000 and 84,000 miles; many occurring before or just outside the 3-year/36,000-mile warranty period. Several owners report the problem occurred within the first few years of ownership.
Symptoms owners cite: Windshield fogs, frosts, or ices over and cannot be cleared using defroster; No air flows from defroster vents despite system being engaged; Air only blows from one location (floor or vents) with no ability to redirect; Low or blocked airflow from all vents; A/C only works on high setting, not on lower settings 1–3; Loud clunking noise from dashboard area prior to failure; Visible moisture/fogging inside cab despite defroster attempt
Repairs/costs cited: Owners cite repair costs between $800–$2,000 depending on labor rates and parts availability. Repair involves replacing the entire heater housing/box rather than just the door (though some dealers only replace the door, leading to recurrence). Dodge replaced the single-tab plastic box design with a two-tab metal version starting in 2007 model year. One owner reports replacing the part three times due to dealer performing incomplete repairs. Repair times can be lengthy due to back-ordered parts and complexity (full dash removal sometimes required).
Recalls/TSBs owners mention: Dodge (Daimler Chrysler) acknowledged the design flaw and re-engineered the heater box with two tabs and stronger materials for 2007 and newer models, yet declined to recall 2002–2006 trucks still under or recently out of warranty. Company typically denies out-of-warranty coverage, citing time/mileage limits. Dealers confirm this is a known ongoing issue but direct owners to pay for repairs. No recalls issued despite widespread complaints.
Windshield Wiper Failure
Windshield wipers stop working, work intermittently, or operate at incorrect speeds. Owners report wipers suddenly stop mid-drive or fail to activate when engaged, despite a recall being in place for this defect in the 2006 model. One owner states Chrysler customer service refused to honor the recall, claiming the VIN was not included.
When: No specific mileage cited in wiper complaints; issues occur while driving in rain or wet conditions.
Symptoms owners cite: Wipers stop working completely without warning; Wipers work intermittently or sporadically; Wipers operate at incorrect speed setting (e.g., set to fast but only works on slowest setting); Wipers do not respond to operator control
Repairs/costs cited: One owner reports waiting for back-ordered replacement parts. Repair shop diagnosing the issue.
Recalls/TSBs owners mention: A recall exists for this defect on 2006 models, but Chrysler customer service has reportedly refused to honor it in at least one case, claiming the VIN was not eligible. Company offered only to 'reimburse' if the recall is expanded, which owner found unacceptable.
Heater Control Malfunction (Mode Selection)
The heater control knob does not direct airflow to the intended location. When a driver selects a mode (floor, defrost, vents), air does not flow from the selected outlet. Multiple owners report heat blowing from the floor when defrost was selected, or vice versa. In some cases, all heat output is directed to one area only.
When: Issues occur after purchase and during normal operation; one repair was performed at $800 cost but problem returned within months.
Symptoms owners cite: Air does not blow from the selected mode (defrost, floor, vents); Heat or air only blows from one location regardless of control setting; Windshield cannot be defogged when defrost mode is selected; Floor receives heat when defrost was selected, creating dangerous fogging conditions
Repairs/costs cited: One owner paid $800 for heater repair including replacement of control switch, mode door actuators, and motor controls, yet the problem returned. Dealer later stated entire dash must be removed and heater box replaced. Another owner reports the deflector door needs replacement, which requires full dash removal.
Insufficient Defroster Airflow / Blockage
The defroster does not produce adequate airflow, or the system appears to work intermittently. Windshield remains fogged or iced despite defroster being engaged. In some cases, the system fails to work at all from new. Owners describe this as a safety issue preventing safe visibility.
When: One owner reports the issue present from the date of purchase (at 1,000 miles); another noticed onset around 22,000 miles.
Symptoms owners cite: Defroster produces little to no air; Defroster works intermittently or only occasionally; Windshield fogs, frosts, or ices over and cannot be cleared; Vehicle may have never defogged properly since purchase
Recalls/TSBs owners mention: In one case, dealer was unable to duplicate the failure and advised the vehicle was operating as designed.
Rear Window Leak
Rear window leaks during rain, allowing water ingress into the vehicle. Mold subsequently grows inside the cab.
When: Water leak discovered two months after rain exposure.
Symptoms owners cite: Water leaks into vehicle during rain; Mold growth inside vehicle
Repairs/costs cited: Dealership replaced rear window and installed new track.
