Heat and A/C stopped working after oil pan swap
Ok, so I recently swapped the oil pan for a new one in my 1991 Firebird 3.1. When I did so I noticed a week later that my heat stopped working. I also noticed that my A/C isn't working.
For the Oil pan change I unbolted everything from the motor (Trans, Motor mounts, starter, etc.) and unbolted the pan from there. I put the new pan in and lowered the motor back onto the mounts and bolted everything up.
So, to get to the point. I turn on the heat and I can hear it engage and try to blow but nothing. Same with the A/C. I'm thinking something got pulled off, disconnected, or kinked up somewhere along the motor being lifted up 3-4 inches to replace the pan.
Any help would be highly appreciated since I can not see anything through my windshield without defrosters. Thanks in advance, Jim.
