Minty 1989 TGP in a NJ auction.

Ok I did some testing and here is what I know. KOEO V is about 13.8 Jumping both cooling fan relays turned both fans on after confirming power to each relay cavity. Also I can see the request for A/C ON is given on the scan tool which should have the fans running as well. Based off what I`m reading from the manual the pcm should ground circuit 335(473) to activate Fan 1(2) when A/C command is ON but that doesnt seem to be happening. A test light connected to battery - will activate the fan when probing either relay circuit and work both relays as well.  So fan motors work, the relays click as they should, the wiring associated between relays and fans seem to be ok aside from the circuit between the pcm and relay not grounding. Visibly the harness is ok, still wrapped up in the factory tape all the way from the fuse box. Schematic for reference I`m a bit stuck now in which direction to go and what to look at.         

My 89 Grand Prix was not in use for many years, the radio degraded in that time. It started to give a lot of pops and bangs. So much it seems to have blown a front speaker in the few moments it has been turned on. The speaker is an easy fix, just remove the dash pad and screw a new one in (16054362 is replaced by 15173233 and can be easily found). My system is a 4 speaker with Remote control head 16075882, the optional Cassette+equalizer 16050912 and steering wheel controls. The amp and receiver (16072780) which is located above the glovebox is the one that typically causes issues. I found the documentation here on the forum, unfortunatley the link for the amp doesn't work anymore: But even better than documentation, I found a common cause and fix for the pops and bangs: I tried exactly this procedure: https://reattaowner.com/roj/component/content/article?id=198:radio-capacitor-replacement-instructions. The 6 green capacitors were indeed shot. I found d4x5mm (not d5x5mm), 1uF, 50V, 105°C replacement capacitors at RS and had a specialist to put them in. The radio now works well, only some very minor pops are still noticable when the volume is turned to 0. I am very happy with the result and recommend this fix. However, I did notice now that my FM tuner apparently only goes up to 104.05MHz... Scanning, or manual tuning to get past 104 make it jump to the bottom of the frequency band again. I wonder if anyone else had a similar issue or fix for this?

Out of curiosity did you end up finding some that worked with your car? Those Amanita posted are discontinued. 

My 1995 Cutlass has a factory CD player. Record company CDs play fine. If I want to play my own burned CDs, I have to burn them at the slowest speed or they will not play. Lately I use a Bluetooth FM transmitter and just play content from my phone.
