TSB 93-1-6: Heater - Poor Heat Distribution or Flow From Outlet

Details

Bulletin Number: 93-1-6 Reference Number: 201104 Publish Date: 10/92 Subject: POOR HEAT DISTRIBUTION OR LACK OF AIR FROM HEATER OUTLET (CHECK FOR PROPER INSTALLATION OF HEATER DUCT) Models Affected: 1992-93 BONNEVILLE MODELS CONDITION: Some owners of 1992-93 Bonneville models may experience poor heater distribution or flow from the heater outlet. This problem is easiest to diagnose by checking to see that the heater outlet duct is properly installed (see illustration). If the outlet is incorrectly installed, the heater air is dumped at the back of the outlet, thus producing little if any flow out the outlet openings. CORRECTION: Check the back of the heater outlet for proper installation. The outlet must be in the track that it slides in. The rear of the outlet has two tabs that must be inserted in the modular duct that it attaches to (see illustration). If it is not in the track or the tabs are not inserted, remove the outlet and install correctly. WARRANTY INFORMATION: Labor Operation No.: D1517 Labor Time: 0.3 hrs.
