Ls Vtec swap in 91 Integra, runs good, started having minor electrical problems that annoy the hell out of me. Rear Defrost doesn't work. INT mode for windshielf wipers doesn't work all the time (if it does its usually just on LOW instead of intermittent) and I get annoying warning beeps...as if i had left the door open or disconnected the seatbelt. HELP

 

PS. It is OBD0 if that helps with a chipped PR3 ecu

 

ECU's dont' run the rear defrosters...or other electrical parts (windows, pwr dl, etc.). You might have wired something wrong..recheck your connections again.

 

did u check all your fuse?

 

It sounds to me more like a dash harness electrical problem. Did all of these problems suddenly occur right after the swap?
