Default Delta 88 Automatic Climate Issue

I was helping a friend fix his 1990 Old Delta 88 today. He wasn't getting any heat at all. His temp gauge would only get to about 130 degrees. So, I replaced his thermostat and it now gets to 185-210 degrees. Then, I noticed his blower is working intermittently. On the High Fan Speed setting (Automatic Climate Controls) the blower hardly works. Sometimes, it will kick in for a few seconds on high, then goes right back to its low setting. So I think the blower is ok, but is this a sensor issue? Since I changed the thermostat it does blow hot air but still not at the correct speed. Any help would be appreciated!

Well, on those older Deltas there is a little door located around the middle of the firewall with 4 wires sticking out of it. Behind that little door is a servo that controls the entire climate control system. Try changing that and it should help! Good luck!
