I have a Uniden PC122 in a '92 Nissan Sentra. When the electric fans kick
on, there is enough noise to cover up the low signals. I have tried running
power from the fuse box and the battery. The power ground is only a foot
long or so. The chassis is grounded next to the radio. The antenna is on the
trunk and has an SWR of 1.05:1 on channel 28 and isn't higher than 1.2:1 on
any channel. Transmit and receive are what they should be other than the
noise. I'm thinking I should try capacitors in the fan motor?

I've got one fan with caps across the motor, a toroid inductor AND quite
a few wraps around a snap together ferrite core. This was good for CB
and 800 MHz. It's still damn strong on 146 MHz and 446 Mhz.

Is your antenna mag-mount or proper mount? Trunk hinges are not good RF
grounds. Get some braid
and connect the sides of the hinge together. Just drill a hole and mount it
right if you're mag-mount.
