relay and codes

i have a 1993 buick lesabre limited. i replaced my blower relay. not knowing electrical that much i disconnected the battery while doing this. after replacement of the relay nothing happened. after about 1/2 hour started car and blower worked perfect. but temp number was blinking. i got the codes and they were 41 and 152. do you know what code 41 is and how to troubleshoot? today i went to walmart and the blower was blowing good cold air. low and behold started car leaving walmart and no blower. got on the highway and accelerated and blower turned on. seemed like it got vacumn. code still blinks. do you have any suggestions?

152 is not possible for OBD1

Those are the OBD-I codes for your model car. 152 is not a OBD-I code, there are no 3-digit OBD-I codes. Who knows why you got it, but hopefully correcting the error code 41 will also correct the 152.

ok, checked on ALLDATA today, and wouldn't you know i forgot my print-outs at school. anyway, your codes are not engine codes, they are auto-HVAC codes. a prefix of 1 means its a stored history code. tomarrow i will get the repair info and post it for you
