After blend door actuator replacement the A/C appears to work normally. The heating system still has the following problems:
THE TWO PRIMARY PROBLEMS ARE LOW HEAT QUALITY AND DEFROST BLOWS ONLY COLD AIR. ALSO LOW VOLUME BLOWER.
On any setting the heat at max (90 deg) does not heat the interior to more than approx upper 60s. A/C temp setting to actual appears correct but heat temp setting to actual is about 10-15 degrees off. Air is just lukewarm when asking for heat.
Even at 90 deg setting when switching to defrost it blows cold air only out the windshield vents.
All air all the time blows out of panel vents and must be manually redirected to floor or defrost by shutting the panel vents. But this may be just how the system operates (?)
Blower appears very low at all settings particularly defrost. It does go higher at manual (turn wheel) but seems low to me.
When switching to vent from any heat setting the air appears to be slightly warmer.
Covering the solar sensor changes nothing regarding defrost but I still don’t know if the solar sensor even has anything to do with the EATC.
What am I missing now?
